[gentoo-user] bareos, anyone?
Does anyone of you use the bareos backup suite with gentoo? I will start to test it and learn the basics as I need some hands-on-experience for a job at a customer. Quick installation went fine, aside from the missing systemd-unit-files (yes, we know ...). I will grab some unit-files from another distro (got some templates already) and adjust them, then file that as a bug with bgo. As I am a longtime amanda-user I would be interested in your experience and the pros and cons from your point of view (and if the ebuild in portage is in any way problematic). Thanks, regards, Stefan

Re: [gentoo-user] gentoo-systemd-only deprecation
Top-posting because my question is about something in the linked threads... In one comment was said the following: Can I ask the systemd people to design a working solution for opting out? I can't support this initiative without such a solution and I would be happy to work with the systemd people to reach it, ie I'll test. This already went before the Council, and the decision was that INSTALL_MASK IS the working solution for opting out. If somebody wants to come up with a better one and propose it they're of course welcome to, but in the meantime, INSTALL_MASK is the official solution. Where is this 'INSTALL_MASK' option for opting out of systemd completely documented? Googling only finds references to this discussion?

If users cooperate opening bugs adding systemd unit files (after testing them in their machines), the coverage is going to grow even faster.

Re: [gentoo-user] My PC died. What should I try?
v...@ukr.net writes: If the system behaves in such an unpredictable way (freezing at a random point), I usually check the following things: - RAM; - bloated capacitors on the Motherboard; - bloated or dried capacitors in the power supply unit; If your PC is only half a year old, it is unlikely that the capacitors dried. But they could easily bloat, especially if they were of bad quality or situated near some hot surface like heat sinks. Testing the power supply needs not only visual analysis. It would be good to attach the oscilloscope to the output and see the voltage level. It should not have large peaks (voltage jumps). But this is usually true for the old units with dried capacitors, as I said. The power supply is older, I re-used it from the PC I had before this one. I hope it causes the trouble, and will try another one this evening. Thanks for this information, this strengthens my confidence that I do not have to buy a new board or CPU. Now I am driving home with a bag of three PSUs I had lent to a friend (and already forgotten). If I were you, I'd tried to temporarily replace the memory with a 100% working module, and if it does not help - replace the power supply unit (if you do not have the necessary equipment to test it thoroughly). I wish I had :) The RAM is okay, I think, I cannot imagine different memory modules to suddenly go bad all at once. And memtest86 found one error only after an hour, while the crashes happen after a few minutes already. And one more simple test: turn on the PC, enter the BIOS setup utility and keep it running in this state. If it runs ok for some time (like a couple of hours), I'd say the problem is in RAM. It once crashed after ten minutes. That was not reproducable, but I did not try that often. Wonko
[gentoo-user] systemd how can I get a service to start after network is up

[gentoo-user] problem getting wifi card to route to internet
Hi. This is not strictly a gentoo problem, but I would like advise
from people on how to get my wifi card to see the internet.
On my new box I have the following card:
00:14.3 Network controller: Intel Corporation Wireless-AC 9560
[Jefferson Peak] (rev 10)
Subsystem: Intel Corporation Wireless-AC 9560 [Jefferson Peak]
Kernel driver in use: iwlwifi
Now, I wanted to serve other computers with this device and so emerged
hostapd. Then after some configuration fooling around with
/etc/hostap/hostapd.conf, I got things to the point where the card
comes up and is seen by other devices.
I set the device up on its own network at 192.168.3.1 by using the
following unit file:
[Unit]
Description=Network Connectivity for %i
Documentation=man:ip
Before=network.target
Wants=network.target
BindsTo=sys-subsystem-net-devices-%i.device
After=sys-subsystem-net-devices-%i.device
[Service]
Type=oneshot
RemainAfterExit=yes
EnvironmentFile=/etc/conf.d/network@%i
ExecStart=/bin/ip link set dev %i up
ExecStart=/bin/ip addr add ${address}/${netmask} broadcast ${broadcast} dev %i
ExecStart=-/bin/bash -c "test -n ${gateway} && /bin/ip route add default via
${gateway}"

/etc/conf.d/postdown@%i.sh"
[Install]
WantedBy=multi-user.target
and the following in /etc/conf.d/network@wlan0
address=192.168.3.1
netmask=24
broadcast=192.168.3.255
and also added the following route
route add -net 192.168.3.0 netmask 255.255.255.0 dev eno1
but still I cannot get packets out to the internet. I can ping
the device from my console, but that is it.
I am not sure whether I am missing something in my hostapd.conf or
somewhere else.
Thanks in advance for any suggestions.

Or with a webapp; we can mix the information with the presentation, why to split them? We are just moving it out of sight, right? No, again, we split the information on a web page from how do we present it to the user, so when something breaks, we know where it did. Imagine that systemd had a bug in its ExecStart= directive. Perhaps it works for the first 5 commands, but it fails in the 6th. Then you would have been stuck for hours (perhaps days) trying to debug your unit file, when it had nothing wrong, really. If instead you put all the logic pertaining to your service in a script, or executable, or whatever, but *clearly separated* from systemd, and you got it working, and it doesn't work with systemd, then you *know* where the problem is. I really believe the proper solution is to clearly separate this stuff. You can abuse the Type=oneshot unit files, or heck, even put everything in a single ExecStart=( command1; command2; command3; ...; commandN). That doesn't mean you should. Just my 0.02 cents.

For the decision between S-ATA and IDE: I can recommend using S-ATA. One reason is that most boards have got only one IDE Channel left, second reason is the S-ATA cable is smaller though the air can pass easier through the pc and third they start to be cheaper than the IDE ones. -- Currently developing a browsergame... http://www.p-game.de Trade - Expand - Fight Follow me at twitter! http://twitter.com/moortier
Re: [gentoo-user] [OT]UPS battery dead?
Unplug all your electronic devices and plug in a lamp with a 100 Watt incandescent light build. With the lamp on unplug the UPS from the wall and see what happens. If the battery is dead it won't last all that long. Gave ~5 mins. So I let it charge for 24 hrs now it gives me 36 mins. Which is wierd; what happened to all that charge? I haven't had to use it for 6-7 mons. Isn't the unit supposed to stay topped-up? Another thing: When I do the remove-the-usb-cable test I don't see the communication lost error in apcupsd.events until I switch the dial-up off and on quickly! In the conf file I have DEVICE: /dev/ttyS[0-3] because the default, /dev/ttyS0, locks out the modem. But why does the UPS need to know about serial ports? It connects by this funny RJ-45/USB cable. I wonder does the manufacturer assume the serial port won't be used? mw __ The new Internet Explorer® 8 - Faster, safer, easier. Optimized for Yahoo!

Re: [gentoo-user] [OT] eee PC crashes on shutdown.
You have to hold down Alt, hold down Fn, hold down PrtSc, release Fn then press the command keys. If you keep Fn held down, U is seen as 4 etc. How do I test it out? Must I induce a freeze somehow or can I just apply it to a working rig? Press Ctrl-Alt-F1 to get to the first VC then press Alt-SysRq S. It should report Emergency sync. None of these maneuvers have any effect whatever. Except getting to the first console. Least that I can see. BTW, when I try getting back to the X console, it's blank. Is this an Xfce4 thing? I remember sysrescuecd which also uses Xfce4 had the same bug/feature. I have to ctrl-c on the first console to get back to the prompt so I can restart X. FWIW Prt Sc and Sys Rq are separate keys on this unit. They share space with Ins and Del, respectively. Prt Sc and Sys Rq are printed in blue and, I assume. are part of the 'fn' system. mw

Re: [gentoo-user] My PC died. What should I try?
Hello! On Fri, 17 Aug 2012 09:50:40 +0200 Alex Schuster wo...@wonkology.org wrote: Hi there! Two days ago, my PC suddenly died, after working fine for half a year. I used myrtcwake as usual to suspend to RAM, and it woke up in the morning. But after two minutes, the screen went blank and nothing, even SysRq, gave a reaction. I tried booting a couple of times again, and sometimes it did not even reach KDM. Now, I cannot even run Grub (from my USB stick) any more, I only see a GRUB string at the top right, then nothing happens. Booting with SystemRescueCD also freezes sometimes. If not, I can make it freeze after seconds by running 'memtester'. Booting good old memtest86 ran for an hour and only found one error, then I aborted, removed three of my four memory modules (4GB each), and tried different ones in the first bank. Memtest86 again did not find much errors, but froze once. Running memtester after booting from SystemrescueCD again makes the thing freeze in seconds. It once also froze while being in the BIOs setup. If the system behaves in such an unpredictable way (freezing at a random point), I usually check the following things: - RAM; - bloated capacitors on the Motherboard; - bloated or dried capacitors in the power supply unit; If your PC is only half a year old, it is unlikely that the capacitors dried. But they could easily bloat, especially if they were of bad quality or situated near some hot surface like heat sinks. Testing the power supply needs not only visual analysis. It would be good to attach the oscilloscope to the output and see the voltage level. It should not have large peaks (voltage jumps). But this is usually true for the old units with dried capacitors, as I said. If I were you, I'd tried to temporarily replace the memory with a 100% working module, and if it does not help - replace the power supply unit (if you do not have the necessary equipment to test it thoroughly). And one more simple test: turn on the PC, enter the BIOS setup utility and keep it running in this state. If it runs ok for some time (like a couple of hours), I'd say the problem is in RAM.

[gentoo-user] systemd-vconsole-setup: Suddenly fails after system rebuild
Hi folks, well, I have a weird issue here: Over the weekend, I switched to the new 17.0 profiles, and as part of that process, did an "emerge -e @world" on my ~x86/systemd machine. Took a while, but that was expected, and I was glad to see that afterwards everything was still working fine ... except for one thing: Strangely, on the newly emerged system, after each boot, I noticed that my desired keymap is no longer set on the virtual consoles. I get an English keymap now, although I have set a German one, as per /etc/vconsole.conf: # cat /etc/vconsole.conf KEYMAP=de-latin1-nodeadkeys FONT=eurlatgr.psfu.gz Now, the settings in this file have not been changed. In fact, no configuration changes have been done along with the world re-emerge. Actually, I can find a trace of something being wrong in the journal: Dec 05 08:44:25 boerne systemd-vconsole-setup[1944]: /usr/bin/setfont failed with error code 65. [...] Dec 05 08:44:26 boerne systemd-vconsole-setup[1944]: Setting source virtual console failed, ignoring remaining ones Dec 05 08:44:26 boerne systemd-udevd[1912]: Process '/lib/systemd/systemd-vconsole-setup' failed with exit code 1. So, /usr/bin/setfont seems to fail. Strange that it obviously didn't do that before the world re-emerge, but it's certainly doing it now. Even more strange, however, is that after login, I can operate setfont manually and it will succeed. In fact, after login I can execute /lib/systemd/systemd-vconsole-setup manually, or do "systemctl start systemd-vconsole-setup.service", and either will complete without error and actually set my keymap and font as desired. My wild guess is that during boot, systemd-vconsole-setup might get called too early by systemd-udevd, when the desired font file is not yet available (probably because still running in initramfs context) or when the virtual console, for whatever reason, is not yet ready. But like I've said, that's just a wild guess, I couldn't really find any proof for that in the journal. Looking at the original systemd-vconsole-setup.service file, things look sane in there, I guess: [Unit] Description=Setup Virtual Console Documentation=man:systemd-vconsole-setup.service(8) man:vconsole.conf(5) DefaultDependencies=no Before=initrd-switch-root.target shutdown.target ConditionPathExists=/dev/tty0 [Service] Type=oneshot ExecStart=/lib/systemd/systemd-vconsole-setup However, as a little test / possible workaround, I decided to create my own systemd unit file that does nothing more but execute /lib/systemd/systemd-vconsole-setup, only at a (hopefully) later stage during the boot process: # cat /etc/systemd/system/vconsole-fix.service [Unit] Description=Fix Virtual Console Before=-.mount ConditionPathExists=/dev/tty0 [Service] Type=oneshot ExecStart=/lib/systemd/systemd-vconsole-setup [Install] WantedBy=multi-user.target And after enabling this unit, things actually work just fine: My keymap is, once again, set up properly on the virtual console right after boot and before I log in or perform any manual steps. Sadly, I'm kind of confused now. I'm really wondering if anyone's ever seen something like that before or otherwise has an explanation for it. I mean, it used to work before, and neither configuration nor package versions have been changed. It's just that everything has been re-build (as PIEs), but I can hardly imagine that this is responsible for the issue. Right now, I'm waiting for a second machine to complete the re-emerge process (might take another while) and am then really curious to see if it suddenly suffers from the same oddity. Other than that, the only idea that I currently have is to keep the workaround deployed and have a look if the issue disappears again by itself just as suddenly as it started, probably with a forthcoming version of systemd or something. Of course, understanding things is always preferrable than just hoping for them to fix themselves, so if someone has a clue, I'd be more than glad to hear about it! :-) Greetings Nils

Yes, as a member of testing, *you* expect things will occasionally break, and it is *your* job to test things, break them, and report bugs. Generally true, but not when something is obviously broken. That means not even its upstream dev bothered to test it. ~arch is for we think this works, but please give it a go in case there are problems. It's *not* for we have no idea if this works because we didn't even try it once. Do you have any idea how much time you can spend with the kind of system testing you propose? About 2 minutes? Enabling the parallel startup thingy and rebooting the machine. There you go :-/ That's a facetious answer, and you're purposely only examining a tiny piece of the testing surface. Hindsight is 20/20, though only if you're lucky. Perhaps they've never seen this type of failure before, and they could add a single test to whatever unit test suite they may be using. Perhaps that's an improvement they can make going forward. To fully test OpenRC, you'd want a two-stage testing harness. The outer stage would generate Gentoo VMs with every plausibly-relevant USE flag permutation crossed against as many automatically-generated permutations of OpenRC configuration as could be considered plausibly encountered. For each generated VM, spin it up. Watch for some kind of watchdog hey, I booted successfully! indicator. Then spin up a testing harness *inside* the VM to ensure all services started and behave correctly. Dump a report to the vmhost detailing that everything went well (or didn't), and hibernate the VM. vmhost looks at the report and decides whether or not to keep the saved VM state. That's an extraordinary amount of testing to do. And that's what I see argued as what ~arch is for; instead of having a script whip up and test hundreds of virtual machines, people running ~arch do that testing. Gentoo devs get reports for the features and combinations that people actually *use*, and can spend less time fixing features nobody is using. (And it's obvious none of the OpenRC devs are using parallel boot themselves, or they would have caught this. Perhaps that's why it's experimental; nobody who actively uses that feature is keeping up with HEAD and offering patches.) -- :wq

Re: [MBZ] SDL a/c not working
Belt, tensioner, shock, spring, a/c compressor are all brand new from Rusty. Compressor was just installed a couple weeks ago. The other parts were done when I installed the 22 head. I will check the speed wiring etc after this weekend. It keeps doing this run then off thing only when the car is cold. Turning the car off and on won't kick it back on. It has to cool off. Luther Peter Frederick wrote: in cool weather, that's about right. You will have to check out the speed sensor, the wiring, and the pushbutton unit, sadly. The wires for the speed sensor can break at the pin on the compressor, or the solder can crack there, causing an intermittant poor connection. Also verify the condition of the belt and tensioner -- the car will run just fine with broken tensioner spring except that the AC will keep kicking out. A slipping belt will do it, and so will a back AC compressor. Check the clutch on the compressor for excessive heat after a short run -- if it slips, the compressor will be shut off by the KLIMA until the ignition is cycled on and off (this is a quick test for a bad clutch or cos-only was a BIG mistake.

What's the expected development effort, what are the services you pay for (binaries, source code, testing, maintenance, ...)? Regarding programmer vs. company, I'd say it depends on what you expect and pay for. If you just want it coded, then the lone programmer is probably as good as the company (since programming itself doesn't really scale well with the number of devs). Extensive testing, on the other hand, is something a team should do. Sure, the lone programmer can write you some unit tests and conduct a system test, but testing itself is a profession of its own and should be done by a second person with the relevant training. But in the end, these issues a minor. It really boils down to whom you trust more. Ask for references, look at their previous work, talk to them, etc. All things being equal, paying 1*x instead of 2*x gives you the chance to pay another 1*x to a second developer if things don't work out with the first one. ;-) Regards, Florian Philipp signature.asc Description: OpenPGP digital signature

I want to use my sysklogd for my syslog, how can I use that with systemd? systemd's journal will be written to a socket if you configure it in /etc/systemd/journald.conf I would check man journald.conf and the option: ForwardToSyslog= and then let your chosen log-daemon listen there.

I synced the tree today just before the emerge. Might I have picked up an inconsistent tree and hence should I resync? Hans de Graaff replied a bit ago; it looks like RUBY_TARGETS in the profiles were not updated after ruby-2.1 was masked. If you re-sync, you should be able to go forward with the update. 6. I have NOT done the eselect ruby set ruby 22. As Hans also mentioned, the upgrade itself will not automatically run the eselect command - my bad. Once you do a depclean and ruby-2.1 is removed, eselect will be run to set the system ruby version to 2.2. Alec

[gentoo-user] OT: looking for info on USB3 to Mini-pcie WiFi module
Hi all, I am looking for info on usb3 to mini-pcie wifi modules - some kind of adaptor? There are a lot of mini-pcie to M.2 on ebay but reading up on mini-pcie it seems they may not be compatible. Does anybody have an idea of one that would work - they are cheap enough to buy and test/throw back on shelf if they dont work but the current two month delivery times are a killer :) My existing wifi AP is getting too old to properly upgrade (Its an old Buffalo G300N running openwrt) so I am building my own - I currently have a gentoo based userland on a raspberry-pi3B using the inbuilt wifi and a realtek usb WiFi 1200ac dongle which is the proof of concept but before I go and purchase more powerful hardware for the controller (looking at an odroid C4 at the moment) I want to ascertain if I can use some of the mini-pcie wifi cards I have via USB3 (one is a 3x3 mimo atheros ac module, others atheros or intel N.) At the end of the day, I am looking for WiFi6 compatibility and a performance boost over the old buffalo (multiple family members are working from home, mostly via wifi which is holding up pretty well so far but I want better :) Yes I could by a bespoke unit but whats the fun in that :) BillK pEpkey.asc Description: application/pgp-keys

Re: [gentoo-user] adding feature to asterisk ebuilt
OK, here is request I've made; I'm not sure I've entered it correctly as it is more like a feature improvement than a bug. http://bugs.gentoo.org/show_bug.cgi?id=92747 To my understanding NVBackgroundDetect is a competition to Digium own faxdetect feature they have incorporated into asterisk. There is no rush for them to implement/incorporate this NVBackgroundDetect code as they are trying to push their own cards. I'm not in favor of the internal cards and prefer ATA unit. No, not everybody needs it; but for me and many like me it would allow us to move fax on an internal extension extension and free up the line (You can use the fax line for an incoming calls). You can read how the NVBackgroundDetect works at: http://www.voip-info.org/tiki-index.php?page=NVBackgroundDetect The code is GPL from Newman Telecom Asterisk has a fax detection code but it only works with ZAP channel (Digium Card) which I'm not in favor (I prefer ATA - external units like Sipura SPA-3000 and/or any other ATA unit). Right.. so if I'm reading this correctly, NVBackgroundDetect is an improvement on Asterisk's own fax-detection code. I have a X100P clone which might not be supported by Asterisk - NVBackgroundDetect detects faxes for ALL cards? I'm not sure if how the code works, I haven't test it yet, but according to Newaman from Telecom nobody reported any problem with their code. Yes, I would say it is an improvement as it works with all other hardware not only ZAP channel cards. Unless this introduces incompatibilities with fax-detect on Digium's ZAP channel hardware, it would seem there's no reason not to include this as part of a default Asterisk install?? I don't think there will be any incompatibility or conflict, it is just an extra module; you can use it or not. It is just seating and idling until you call it into action. I've the code from Newman Telecom but I'll file an ebuild request as you suggested. The code would be suitable for many like me that don't use ZAP channel but would like to have/take advantage of fax-detection. Please post a link to the bug. If you're not comfortable hacking the ebuild yourself I might well have a crack at it - I have Asterisk hardware sitting here waiting for me to find the time to implement it. Here is the link: http://bugs.gentoo.org/show_bug.cgi?id=92747 As I said I have the code and can email it to you; but you can as well get it from the Newman Telecom directly. I was able to compile NVBackgroundDetect using CVS version but ver.1.0.6 and 1.0.7 has a bug with SIP and dtmf inband; so I went back to Gentoo 1.0.5 versio; However I'm using now dtmf out of band dtmfmode=rfc2833 and it is working OK. -- #Joseph -- gentoo-user@gentoo.org mailing list

RedHat has a vested interest in doing this right (it's the product they sell) and they have more engineering resources to apply to the problem than I can ever raise. The odds favour RedHat often getting this right and me often getting it wrong, simply because I don't have the unit testing facilities required and my employer doesn't employ OS builders. I won't permit Gentoo to be used in production here for precisely that reason - I can't provide the test guarantees the business and shareholders demand. Yes, I agree that RedHat might be a better choice, if you can afford it (although there are some counter-arguments since they practically maintain kernel-forks because of heavy backporting, but I am unable to make a definite opinion on this). But that was not the point of my claims, so I don't see an argument. The argument that this particular setup may be less tested is a valid one. But less tested also means less commonly known exploits and testing these setups is a win-win for users and upstream. Whether you like it or not... whenever you install software on a server, you become a tester at the same point. Proper testing carries a onerous burden. I've yet to find a enterprise anywhere in the world that does it right outside of their core business. Instead, they pay someone else to do it. Yeah, the kernel has _zero_ proper testing in the sense of software engineering. RedHat does not really improve that (e.g. unit tests and whatnot). Greg said why that's almost impossible, especially because the internal API changes way too frequently. Still unable to find a real counter-argument.

Frank,
As best I can tell so far none of the Linux tools will tell you
that the sectors are 4K. I had to go to the WD web site and find the
actual drive specs to discover that was true.
however if you use dmesg:
$ dmesg | grep ata
ata1: SATA max UDMA/133 irq_stat 0x00400040, connection status changed
irq 17
ata2: DUMMY
ata3: SATA max UDMA/133 abar m2...@0xf6ffb800 port 0xf6ffba00 irq 17
ioatdma: Intel(R) QuickData Technology Driver 4.00
ata3: SATA link down (SStatus 0 SControl 300)
ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
ata1.00: ATA-7: ST9160823ASG, 3.ADD, max UDMA/133
ata1.00: 312581808 sectors, multi 8: LBA48 NCQ (depth 31/32)
...
you can look up your drive model number (in my case ST9160823ASG) and
find out the details. (That's a Seagate Momentus 160Gb with actual 512
byte sectors).
saves having to open up your laptop / pc if you didn't order the drive
separately or you've forgotten.

Bugs are bugs, period. And they get reported and fixed. Bugs are not equal. They differ in at least two dimensions: significance depending on the component affected and severity of the bug itself. Bugs in the critical system components are critical to the whole system. Yeah, that's why we have unit testing and QA teams and stable and unstable releases, etc. Every decent project has QA and unit tests one way or another. But the larger project is, the more bugs it has. And I do not want bugs in PID 1, that's why it should be small and sound, not bloated (even with some components split as separate binaries) and broken by design. If Libreoffice or browser segfaults, some data may be lost and inconvenience created, but the system will continue to run. If PID 1 segfaults — everything is lost, you have a kernel panic. And the world will end? The same happens if the kernel has an error. Kernel has mature error correction infrastructure (Oops handling) and much wider community. That's why critical components should be as simple and clean as possible. Like the kernel? You call that simple? Don't mix user space and kernel space, please. There are more secure by design micro kernels out there (like Hurd), but they're out of the scope of this discussion. I'm sorry, but you are (IMO) wrong: critical components should be thoroughly tested and debugged, and have integrated unit testing, and a large enough group of volunteers to test new releases before they go into the general public. You're pointing to valid issues, but not to the whole picture. Critical components should _start_ from good design, sound modular architecture and _then_ with QA and testing. You're omitting the most important stuff, though. SysVinit code size is about 10 000 lines of code, OpenRC contains about 13 000 lines, systemd — about 200 000 lines. If you take into account the thousands of shell code that SysV and OpenRC need to fill the functionality of systemd, they use even more. If that code will fail, this wouldn't be critical at system level. Thus scope of fatal error is limited. Even assuming systemd code is as mature as sysvinit or openrc (though I doubt this) you can calculate probabilities of segfaults yourself easily. I don't care about probabilities; I care about facts: FACT, I've been using systemd since 2010, in several machines, and I haven't had a single segfault. FACT: almost no bug report in systemd involves a segfault in PID 1. You need facts? Here is one for you (systemd-208): http://fly.osdn.org.ua/~mike/img/misc/systemd-segfault.jpg Looks broken. Broken by design. The worst form of broken. By your opinion, not others. That is not just an opinion. There is a science and experience behind system's design. Yeah, what do you think about Greg Kroah-Hartman, Linus' right hand, or Keith Packard of X.org fame? None of them works for Red Hat; both of them know more about Unix and Linux than you and me together, and both of them promote systemd. I respect Greg for most of his work, but this doesn't mean he is an oracle we need to adhere to. But in FOSS reputation is not that important, though clean technical reasons are. And all that science was ignored during systemd architecture process if there was any at all. You should read systemd-devel and Lennart's blog posts before saying something like that. I did. I read that blog. No valid reason were found (if we're comparing systemd to what is outside of systemd's world, not only to bare sysvinit). But what I found it that blog is a lack of thorough project design (it looks like many components were added by the fly without preliminary planning) and a lot of religious statements.

On Tue, Nov 29, 2011 at 9:10 AM, Mark Knecht markkne...@gmail.com wrote: On Mon, Nov 28, 2011 at 8:10 PM, Michael Mol mike...@gmail.com wrote: Hi Michael, Welcome to the world of what ever sort of multi-disk environment you choose. It's a HUGE topic and a conversation I look forward to having as you dig through it. My main compute system here at home has six 500GB WD RE3 drives. Five are in use with one as a cold spare. I'm using md. It's pretty mature and you have good access to the main developer through the email list. I don't know much about dm. If this is your first time putting RAID on a box (it was for me) then I think md is a good choice. On the other hand you're more system software savy than I am so go with what you think is best for you. Last time I set up RAID was three or four years ago. Two volumes, on RAID5 of three 1.5TB drives (Seagate econo drives, but they worked well enough for me), one RIAD0 of three 1TB drives (WD Caviar Black). The RAID0 was for some video munging scratch space. The RAID5, I mounted as /home. Those volumes lasted a couple years, before I rebuilt all of them as two LVM pvgs, using the same drive sets. 1) First lesson - not all hard drives make good RAID hard drives. I started with six 1TB WD Green drives and found they made _terrible_ RAID units so I took them out and bought _real_ RAID drives. They were only half as large for the same price but they have worked perfectly for nearly 2 years. What makes a good RAID unit, and what makes a terrible RAID unit? Unless we're talking rapid failure, I'd think anything striped would be faster than the bare drive alone. 2) Second lesson - prepare to build a few RAID configurations and TEST, TEST, TEST __BEFORE__ (BEFORE!!!) you make _ANY_ decision about what sort of RAID you really want. There are a LOT of parameter choices that effect performance, reliability, capacity and I think to some extent your ability to change RAID types later on. To name a few: The obvious RAID type (0,1,2,3,4,5,6,10, etc.) but also chunk size, metadata type, physical layout for certain RAID types, etc. I strongly suggest building 5-10 different configurations and testing them with bonnie++ to gauge speed. I didn't do enough of this before I built this system and I've been dealing with the effects ever since. I'm familiar with the different RAID types and how they operate. I'm familiar with some of the impacts of chunk size, what that can mean in impacts on caching and sector overlap (for SSD and 2TB+ drives, at least). The purpose of this array (or set of arrays) is for volume aggregation with a touch of redundancy. Speed is a tertiary concern, and if it becomes a real issue, I'll adapt; I've got 730GB left free on the system's primary disk which I can throw into the mix any which way. (use it raw as I currently am, or stripe a logical volume into it...) 3) Third lesson - think deeply about what happens when 1 drive goes bad and you are in the process of fixing the system. Do you have a spare drive ready? Don't plan to, but I don't plan on storing vital or operations-dependent data in the volume without backup. These are going to be volumes of convenience. Is it in the box? Hot or cold? What happens if a second drive in the system fails while you're rebuilding the RAID? Drop the failed drives, rebuild with the remaining drives, copy back a backup. It's from the same manufacturing lot so it probably suffers from the same weaknesses. My decision for the most part was (for data or system drives) 3-drive RAID1 or 5-drive RAID6. For backup I went with 5-drive RAID5. It all makes me feel good, but it's too complicated. 4) Lastly - as they say all the time on the mdadm list: RAID is not a backup. Absolutely. I've had discussions of RAID and disk storage many times with some rather apt and experienced friends, but dmraid and btrfs are relatively new on the block, and the gentoo-user list is a new, mostly-untapped resource of expertise. I wanted to pick up any additional knowledge or references I hadn't heard before. :) Personally I like your idea of one big RAID with lvm on top but I haven't done it myself. I think it's what I would look at today if I was starting from scratch, but I'm not sure. It would take some study. It's probably the simplest way forward. I notice there are some network-syncing block devices in the kernel (acting as RAID1 over a network) I'd like to play with, but I haven't done anything with OCFS2 (or whatever other multi-operator filesystems are in the 3.0.6 kernel) before. Hope this helps even a little, Mark Certainly does. Also, your email has a permanent URL through at least a couple mailing list archivers, so it'll be a good thing to link to in the future. :) -- :wq

It's as I thought - your data is accurate but rrd has been given a
completely wrong method to derive the graphs.
Munin graphs for section "Network" do not have to be in a file called
"network" - it's just a category and the plugin defines what web-page
section it must be in. In your case, the relevant plugin is
netstat_multi which doesn't often get installed. It's data source is
"netstat -s" so grep that output for "timeout" to see it.
Timeouts are cumulative counters, they do not get less till they wrap
around. So to scale them, the plugin gets the rrd file to subtract
previous reading from current reading and divide by the time interval to
get the timeouts/sec. This is all done inside rrd when the data files
are updated (it's quite a lot of magic)
That plugin sets the graph type to DERIVE
(/etc/munin/plugins/netstat_multi around line 190. I feel it should be
GAUGE or COUNTER.
The proper reference on rrd is
http://oss.oetiker.ch/rrdtool/doc/rrdcreate.en.html
and the munin docs are
https://munin.readthedocs.org/en/latest/index.html
You must edit the plugin file and IIRC recreate the rrd, you will lose
all past info (can't be helped).

hmmm, but what should I use for the source ip, I only assign those
when I bring the interface up when I start the interface -- I have
something like this:
[Unit]

/etc/conf.d/postdown@%i.sh"
[Install]
WantedBy=multi-user.target
and the /etc/conf.d/network@eno1 is
address=192.168.0.1
netmask=24
broadcast=192.168.0.255
So, before I run this, I don't think the card has any ip address, does
it?

Set systemd.log_level=debug in your command line, and post the exit

I had debug in the command line by itself, would that make the correct

I don't think is necessary, I may have found the real problem (see below).
Some units did start, but most did not. Whenever I tried to

That sounds like a problem with the cgroups hierarchy (which uses a

systemd will not (AFAIK) start your network, and before the 209 or 210

ifconfig, etc.) to do it. Now it includes networkd, but you need to
set up .network files (like .service files) to configure it. See [1].
So we have made some progress, but still a long way to go yet. Note
also, that I am not booting into a display manager, just a regular
console.
What a lot of work just to get the system booted!
Well, you have a setup that is not, by any means, simple. Also, in my
experience old LVM configurations seem to cause a lot of troubles to
bring to what systemd expects.
John, could you also post here your kernel config? Those cgroups
errors *may* be related to some missing functionality from the kernel.
[snip kernel config]
John, your kernel is incorrectly configured to be used by systemd.
When you installed systemd, a warning should have appeared about some
missing configure options; you either didn't saw or ignored those
warnings. Install systemd again so you can see them.
From what I can tell, you are missing *AT LEAST* the following options:
CONFIG_AUTOFS4_FS
CONFIG_DMIID
CONFIG_FANOTIFY
CONFIG_INOTIFY_USER
CONFIG_PROC_FS
CONFIG_SYSFS
John, if you don't set them, systemd *CANNOT WORK PROPERLY*. They are
mandatory. I'm surprised you are able to boot to a semi-working state.
Yes, migrating to systemd is a lot of work. But if you don't see (or
ignore) your system messages, that work gets multiplied several times.
Reconfigure, recompile, and reinstall your kernel (don't forget to
reinstall the modules!), regenerate your initramfs, update lilo (if I
remember correctly, you need to run lilo -something-or-another every
time you change kernel and/or initramfs), and try again.

John, your kernel is incorrectly configured to be used by systemd.
When you installed systemd, a warning should have appeared about some
missing configure options; you either didn't saw or ignored those
warnings. Install systemd again so you can see them.
From what I can tell, you are missing *AT LEAST* the following options:
CONFIG_AUTOFS4_FS
configured as a module.
CONFIG_DMIID
set to Y
CONFIG_FANOTIFY
set to y
CONFIG_INOTIFY_USER
set to y
CONFIG_PROC_FS
set to y
CONFIG_SYSFS
set to y
I beg your pardon; GMail cut the config file and I didn't notice.
Well then, please send me privately the output from journalctl -b.

Cool, one problem less.
Now for some systemd problems. The root file system was read only
when
I logged in, but I could remount it rw -- not sure why this was
happening.
Set systemd.log_level=debug in your command line, and post the exit
from journalctl -b.
I had debug in the command line by itself, would that make the correct
log_level? The file is quite large, should I send it to you privately?
I don't think is necessary, I may have found the real problem (see below).
Some units did start, but most did not. Whenever I tried to
start one manually, I got a message like the following:
[snip]
No matter what unit I tried to start I would get such a message about
the service.mount.
That sounds like a problem with the cgroups hierarchy (which uses a
virtual filesystem). I don't remember seeing a problem like that
before.
Also, even though my network names were correct, they did not come up,
but I will try to look in the logs to see why not.
I wrote a service file to start my network adaptors, here it is:
network@.service
[Unit]

Wants=network.target

BindsTo=sys-subsystem-net-devices-%i.device

ExecStop=/usr/bin/ip addr flush dev %i
ExecStop=/usr/bin/ip link set dev %i down
[Install]
WantedBy=network.target
Did you enabled network@ifaca.service? Also, WantedBy=network.target
doesn't do what you probably think it does (check [1]... and BTW, I
forgot my last footnote, is now on [2]).
I would use WantedBy=multi-user.target.
systemd will not (AFAIK) start your network, and before the 209 or 210
version it needed helper program (NetwokrManager, connman, ip,
ifconfig, etc.) to do it. Now it includes networkd, but you need to
set up .network files (like .service files) to configure it. See [1].
So we have made some progress, but still a long way to go yet. Note
also, that I am not booting into a display manager, just a regular
console.
What a lot of work just to get the system booted!
Well, you have a setup that is not, by any means, simple. Also, in my
experience old LVM configurations seem to cause a lot of troubles to
bring to what systemd expects.

Then tell your devs to develop against these. When they have finished their modules (classes, units, whatever), it is your job to integrate these modules and see whether they work together as expected. If they don't, improve your specs and tests and give the code back to the devs for another iteration. I favor the second approach, especially as there are tools available to help you and it is safer against reverse-engineering. Both of these approaches are going to involve a lot of overhead (the second more so that the first). I would _guess_ than approach 2 will add at least 50-100% overhead. IOW, there's a pretty good chance that writing the whole thing yourself would take less of your time than designing, specifying, coordinating, integrating, testing and managing approach 2. [...] Sure. But it will be fun! ;) ... Just kidding. Unless specifications, inline interface documentation (doxygen, javadoc) and unit tests were already planned or even done (kudos if you actually do this while developing), you are probably right concerning the overhead. Of course it all depends on your development environment. When you get into the embedded, real-time, high-performance, high-security or high-redundancy realm, specifications etc. tend to become less overhead in comparison to actual coding and algorithmic effort. There are reasons why in some environments it is even affordable to create two independent implementations and then choose the better one.

Re: [gentoo-user] {OT} hire a programmer or company?
I'm debating whether I should hire an expert programmer for $X/hour, or a company of expert programmers for $2X/hour. It makes sense from a financial perspective to hire programmers directly, but I wonder if there are benefits to hiring a really good company. I'm sorry this is OT, but I bet you guys have some seriously good insight on this. Thanks, Grant For starters, you could give us a bit more insight into the kind of project we are talking about. What's the expected development effort, what are the services you pay for (binaries, source code, testing, maintenance, ...)? The project is made up of various and ongoing scripting tasks for a relatively complex website. Regarding programmer vs. company, I'd say it depends on what you expect and pay for. If you just want it coded, then the lone programmer is probably as good as the company (since programming itself doesn't really scale well with the number of devs). That's a really good point. Extensive testing, on the other hand, is something a team should do. Sure, the lone programmer can write you some unit tests and conduct a system test, but testing itself is a profession of its own and should be done by a second person with the relevant training. But in the end, these issues a minor. It really boils down to whom you trust more. Ask for references, look at their previous work, talk to them, etc. Can you tell me what sort of positive and negative things to watch out for? All things being equal, paying 1*x instead of 2*x gives you the chance to pay another 1*x to a second developer if things don't work out with the first one. ;-) Once I need more than one developer (which could come sooner rather than later due to the availability of these guys) am I likely to struggle managing them? I've read a bit about Agile software development and I plan to read a lot more. Is that the way to go? Would hiring a company make management a non-issue from my perspective? - Grant Regards, Florian Philipp

RedHat has a vested interest in doing this right (it's the product they sell) and they have more engineering resources to apply to the problem than I can ever raise. The odds favour RedHat often getting this right and me often getting it wrong, simply because I don't have the unit testing facilities required and my employer doesn't employ OS builders. I won't permit Gentoo to be used in production here for precisely that reason - I can't provide the test guarantees the business and shareholders demand. The argument that this particular setup may be less tested is a valid one. But less tested also means less commonly known exploits and testing these setups is a win-win for users and upstream. Whether you like it or not... whenever you install software on a server, you become a tester at the same point. Proper testing carries a onerous burden.

I will consider this ... As I understand things here: the former admin *tried to* setup multipath and somehow got stuck. That's why it isn't running and not used at all. He somehow mentioned this in an email back then when he was still working there. So currently it seems to me that the storage is attached via "single path" (is that the term here?) only. "directly"= no redundancy That means using the lpfc-kernel-module to run the FibreChannel-adapters ... which failed to come up / sync with a more recent gentoo kernel, as initially mentioned. (right now: 4.1.15-gentoo-r1 ... ) I consider sending a Debian-OS on a SSD there and let the (low expertise) guy there boot from it. (or a stick). Which in fact is risky as he doesn't know anything about linux. Or I simply wait for my on-site-appointment and start testing when I am there. Maybe I am lucky and the debian lpfc stuff works from the start. And then I could test multipath as well. I assume that maybe the adapters need a firmware update or so. - The current gentoo installation was done with "hardened" profile, not touched for years, no docs so it somehow seems way too much hassle to get it up to date again. Additionally no experts on site there, so it should be low maintenance anyway.

Recent versions of > glibc use this to implement the posix_spawn() function. I guess... from reading the man page. There is a simple test to verify my clain for vfork(): bosh may easily be configured for various behavior. If you like a bosh that does not use vfork() just call: cd sh smake clean smake COPTX=-DNO_VFORK If you run tests like: CONFIG_SHELL=$shell $shell ./configure in the directory "autoconf" from the schilytools: http://sourceforge.net/projects/schilytools/files/ (first run "rm *cache"), there is a significant performance win on Solaris for the version that uses vfork() - 20% less kernel CPU time. On Linux, there is a too little win for the same comparison. On Solaris, a vfork() call (check with truss -c) is takes only 1/3 of the time of a fork(), on Linux the win is only 30%. The total performance win for bosh executing configure using vfork() on Solaris is 10-15%, on Linux the total win is only 3%. Note that Linux copied the Solaris concept to implement a normal fork() with copy on write mmaps to the parent. So the only difference between fork() and vfork() is the handling of the address space description for the processes in the kernel. I would be happy, if there could be a way to get the same vfork() performance win on Linux as seen on Solaris. BTW: I forgot to mention that the unit tests for bosh are used this way: - first compile schilytools by running smake from top level. - Then chdir to "sh" and call "smake tests", see the global code in $SRCROOT/tests and the specific code in sh/tests Jörg -- EMail:jo...@schily.net(home) Jörg Schilling D-13353 Berlin joerg.schill...@fokus.fraunhofer.de (work) Blog: http://schily.blogspot.com/ URL: http://cdrecord.org/private/ http://sf.net/projects/schilytools/files/'

If with default settings your RAM is playing up, update the firmware and check again. I tend to knock back the DRAM timings a bit on O/C'ed boards and this helps with stability. It goes without saying if default settings give you an unstable system, you should not try overclocking it. :-) PS. I use Corsair PSUs and always spend more on them to make sure it is not the cheapest model. A middle of the range modular unit comes with Japanese capacitors and has not caused me problems in various builds. In cheaper models I've ended up replacing the capacitors without waiting for the PSU to fail first - cheap PSUs always fail on me at the end. -- Regards, Mick signature.asc Description: This is a digitally signed message part.

maxim wexler blissfix at yahoo.com writes: group, Only 2.8mins left? The UPS unit, fairly common I suspect, is a Back-UPS ES 350 and less than a year old. It only saw service once last year during an electric storm when the house power failed for a few minutes. Why isn't it charging. Or is it? 13.4 volts looks good on a 12V battery. I'm not sure I'd trust all the numbers. One easy thing to do is to, just swap in another (hopfully 7AH) standard 12V battery), give it a few days, and see what the numbers say. If you have lots of UPS's then getting a low cost 12V batter tester for 'Jell-Cell' batteries is not a bad idea. If you see signs of corrosion, toss the battery to the nearest recycle agency near you. It says BATTDATE 2000-00-00. Huh? Ignore. This looks like a default firmware value if not is correctly entered during manufacture or by the person that does maintenance. Some firewares include it, but the manufacture does not have a software application, where the info can be updated. Gel-Cell batteries are not smart (i.e. no microp) so there is no way for the battery to provide this info, to the UPS firmware. It's gimmickery. I'd like to test it further but the apcupsd manual recommends at least 5mins time left. I'd use manual testing techniques with the battery removed from the ups. You could have leaky or degraded circuitry in the ups. I canabalize old ups for good circuits and batteries and such. If you have several similar models you can do the same. Best to buy UPS in qty 2 or more to cannabalize parts. Never by a ups that does not use the standard 7AH or multiples of that standard battery. The further away from those batteries you get, the more you'll get 'ripped' at replacement time. One more thing. The smaller UPSs are of poor quality. I usually never bay an ups with less than 1KVA rating, although 800VA seem to be OK. The smaller ones just dye as the electronic swithcing circuits (how AC is made from DC) are just crappy and often fry or fatigue. Try not to run a UPS at more than 40% of the duty cycle, if you want it to last very long. Hooking up any arrangement of AC lighting will allow you to see how the battery performs over test intervals of 5,10,20,30 minutes. An amp meter, the kind that clamps around the power cord will give you the current draw of the load. From those numbers and the measured voltage across the battery, you can plot performance curves. After you do a few batteries, you can just watch the lights and pretty much tell if a battery is cooked. Battery testers are also cool, and convenient. If you are in the US, here is a great supplier for replacement batteries. They have an 8AH replacement of the standard 7AH battery (same form factor) that is usually less expensive, better quality and will give you a 1/7 longer life, nominally, Battery Wholesale Dist. 40120 Industrial Park Circle Georgetown, TX 78626 800 365 8444 not sure the website... hth, James

2. I do not have "ruby" or "RUBY" anywhere in the tree rooted

Of course, you'll have problems saving any settings with a write- protected /etc, so JFFS2 may be a better option. This is a filesystem specifically for flash driver, that avoids repeated writing to the same part of the disk. Or, of course, you could simply mount the filesystem ro. Ah, there's always a smart guy out there. ;-) Why didn't I think of that? Good point! There much be a way to do this sort of thing, again because I have the install CD as an example. For me this is about how to make a quiet MythTV frontend machine, not a 'Gentoo PC.' No hard drive is less noise. My thought was that once the machine was configured I'd like to lock the flash and never write ANYTHING to it. What about the MythTV data? Is that on another box, networked? Exactly. We have a server with lots of storage elsewhere on the network. This flash drive machine has no purpose other than playing that MythTV recordings. It's just a single function box. Although the first unit has a DVD drive in it since I had to build Gentoo from a universal CD I figure that long term I don't even need that since the picture playing a DVD from Myth is nowhere near as good as playing for our DVD players. The only time I'd possibly do anything on the flash was to update the system, maybe once every few months. Other than that if the machine is turned on and playing TV shows then I'd be happy with no logging or any type and the drive doesn't change at all. It sounds like you need something like one of these, which keep the card inside the box, and treat it as a hard disk (but silent). More or less. It could be inside or outside. What I sort of liked about the external USB flash drive was the idea that I could possibly learn to build the distro in a chrooted environment on my laptop, for instance, and then write it to multiple flash drives for multiple boxes. I've set this system up here, but I'm also building units for my parents who live 350 miles away. Right now they have a Gentoo backend and an XBox frontend. If a significant rev of Myth or Gentoo came along my thought was I could write it on one of this little guys, test it here, and then send it to my dad with instructions to power down, replace the old flash drive with the new flash drive, boot up, and he's running again. He sends me back the old flash drive and we can go through that process whenever we want. I could also ftp a new version to his Myth backend box with instructions on how he could overwrite the old drive but if somethig goes wrong then the unit doesn't work at all. Another possibility is to skip the flash drive completely, put in a cheap CD and then build essentially a Gentoo LiveCD that boots the system and starts Myth. No hard drive, no flash drive and probably the cheapest solution. Might be more noisy though if the drive continues to spin forever... Maybe there's instructions out there on how to do this sort of thing but I haven't found them yet. Removing all hard disks would also reduce the amount of heat generated, so you could reduce fan speeds to make it even quieter. Exactly my though. I bought the 512MB flash drive for $42 on sale yesterday. If I remove the hard drive and the DVD drive then a Pundit-R comes out at about $275-$300 which is at least reasonable, but still a lot higher than Tivo which sells the hardware at a loss and then makes it up in subscription costs.

Because features means complexity. Yeah, like the kernel. Complexity means bugs. Bugs get reported, bugs get fixes. Life goes on. You didn't answered this, did you? Bugs are different. Bugs are bugs, period. And they get reported and fixed. Bugs in the critical system components are critical to the whole system. Yeah, that's why we have unit testing and QA teams and stable and unstable releases, etc. If Libreoffice or browser segfaults, some data may be lost and inconvenience created, but the system will continue to run. If PID 1 segfaults — everything is lost, you have a kernel panic. And the world will end? The same happens if the kernel has an error. That's why critical components should be as simple and clean as possible. Like the kernel? You call that simple? I'm sorry, but you are (IMO) wrong: critical components should be thoroughly tested and debugged, and have integrated unit testing, and a large enough group of volunteers to test new releases before they go into the general public. SysVinit code size is about 10 000 lines of code, OpenRC contains about 13 000 lines, systemd — about 200 000 lines. If you take into account the thousands of shell code that SysV and OpenRC need to fill the functionality of systemd, they use even more. Also, again, systemd have a lot of little binaries, many of them optional. The LOC of PID 1 is actually closer to SysV (although still bigger). Even assuming systemd code is as mature as sysvinit or openrc (though I doubt this) you can calculate probabilities of segfaults yourself easily. I don't care about probabilities; I care about facts: FACT, I've been using systemd since 2010, in several machines, and I haven't had a single segfault. FACT: almost no bug report in systemd involves a segfault in PID 1. All of them are different tools providing one capability to systemd as a whole. So systemd is a collection of tools, where each one does one thing, and it does it well. By your definition, systemd perfectly follows the unix way. no, it isn't. How are those binaries talk to each other? dbus, which is about to be integrated into the kernel with kdbus. And this is a very, very bad idea. Looks like you don't know matter at all: to begin with kdbus protocol is NOT compatible dbus and special converter daemon will be needed to enable dbus to talk to kdbus. kdbus uses a different wire protocol than dbus; but for clients that doesn't matter; libsystemd-dbus will offer a compatibility layer (talk about standard and replaceable), so if your application uses dbus today, it will work with kdbus. Of course, new applications will take advantage of the new features of kdbus. The whole kdbus technology is very questionable itself (and was forcefully pushed by RH devs), Sorry, but it's you who doesn't know the matter at hand: kdbus was (and is) written by Greg Kroah-Hartman, Linus' right hand, and who works for the Linux Foundation. anyway it is possible to disable this stuff in kernel and guess what will be done on my systems. Good for you. Guess what will be done in mine? Looks broken. Broken by design. The worst form of broken. By your opinion, not others. That is not just an opinion. There is a science and experience behind system's design. Yeah, what do you think about Greg Kroah-Hartman, Linus' right hand, or Keith Packard of X.org fame? None of them works for Red Hat; both of them know more about Unix and Linux than you and me together, and both of them promote systemd. I mean, I myself know a thing or two about computing and Linux, and I promote systemd (and nobody pays me, BTW), but obviously you don't need to believe in my credentials. And, no offense, but I will always give more weight to the words of Greg Kroah-Hartman or Keith Packard (to name only two), instead of a random user in gentoo-user. There are knowledgeable people who are against systemd. But usually they don't give *technical* sound reasons. And all that science was ignored during systemd architecture process if there was any at all. You should read systemd-devel and Lennart's blog posts before saying something like that. I did.

[gentoo-user] Re: openrc-run for containers
Hi,
I've got the integration working how I imagined. It is using s6-svscan to
manage the containers, hopefully not abusing something. General idea is to
have supervision control over containers, ie to allow start up in a given
runlevel, have the ability to manage dependency start between given
containers and start/stop using openrc (referenced
https://wiki.gentoo.org/wiki/S6).
Assuming containers are already running, ie given instance of whoami
container:
*docker run -p 80:80 -d -it --name whoami traefik/whoami*
The "run" script, /var/svc.d/whoami/run:
#!/bin/execlineb -P
exec docker start -a whoami
The "finish" script, /var/svc.d/whoami/finish
*#!/bin/execlineb -Ps6-permafailon 60 1 2 exit*
The init.d, conf.d. Cat /etc/conf.d/container.whoami:
*INSTANCE=whoami*
Cat /etc/init.d/container:
*#!/sbin/openrc-rundescription="A supervised test service with a
logger"supervisor=s6s6_service_path=/run/openrc/s6-scan/${INSTANCE}depend()
{ need s6-svscan}stop_pre() { docker stop ${INSTANCE}}*
Finally, [openrc-run, ln -s /etc/init.d/container
/etc/init.d/container.whoami] /etc/initd.d/container.whoami start, stop
work as expected (docker ps |grep whoami does not return anything, after
running "/etc/init.d/container.whoami stop"):

[ ok ]
root@h003 /e/init.d # s6-svstat /run/openrc/s6-scan/whoami
up (pid 6722) 3 seconds
The goal of all this has been to incorporate containers into
/etc/runlevels. I am not sure if there is a better way, have I missed
something by not using s6-overlay or the like? I am not familiar enough to
know.
An outstanding issue, in the s6 run script, i would like to parametrize the
instance name, I don't know how to do it, as it is currently hard coded:
The "run" script, /var/svc.d/whoami/run:
#!/bin/execlineb -P
exec docker start -a *whoami*
But once that is done, then all running containers could be incorporated by
updating the conf.d for INSTANCE name, templating a /var/svc.d/
folder and linking to /etc/init.d/container, ie:
/etc/init.d/container.whoami
/etc/init.d/container.cadvisor
/etc/init.d/container.traefik
[put under control of s6]
/etc/runlevels/20/s6-svscan
...
This is kind of asymmetric, ie container start is in s6, whereas stop
[docker] is in openrc, but I am not seeing a different way, the goal is to
have robust services running. When system boots, s6-scan will start all the
containers automatically, but then further operations, ie for things like
manual failover etc, is possible using standard platform openrc -
effectively docker - start/stop commands.
kind regards

No, if you have the same wrong on both sides, the LEDs will still show correct blinking order. Think of it like this: If you use order 7-5-3-1-2-4-6-8 on both sides, blinking LED 1 on one side will blink the same LED on the other side because they both connect to wire 7. But the twisted pairs that should be twisted are no longer because now you connected pair 1 in the connector to wire 7 and 5 which belong to different pairs in the wire. The wire twists pair (7,8) and (4,5). On the long run, interference now cannot be canceled out because this only works if wires are twisted in the same pair. The connector (and ethernet standard) expects the following pairs on the connector: A-A-B-C-C-B-D-D 1-2-3-4-5-6-7-8 For electrical reasons it also expects a white wire alternating with a colored pair, which makes the following pairs: A = (1,2) B = (3,6) C = (5,4) D = (7,8) Or: A-a B c-C b D-d ^_^ With the capital letters being either all white or all colored (this doesn't depend as long as it's the same on both sides). You could open the problematic wall outlets and check the cabling yourself. Keep in mind that unmounting the wall outlet may make the problem of bent cables even worse due to moving and bending the wires even more. Usually, the company that installed the cabling should've done a frequency spectrum test on each wire pair. If you didn't get it you should ask for it. In my company, we deny any network problems of our delivered equipment unless such a test has been done and presented to us. Such a test may cost a few extra bucks but should be part of such an installation (done by the electrician before handling the project over to its customer). Depending on the inside of the RJ45 wall outlet, you can fix it yourself. For the cheaper LSA based internal connectors you need an LSA tool (it's inexpensive). Don't try to use a screw driver to mount the wires. The more expensive modular connectors are easy to mount: Just insert the wire pairs properly into the holes, properly and cleanly cut the wires off the other end, and push the connector module in place (take care of proper alignment). The modular connectors also properly connect shielding, so properly connect that. Usually those connectors come with a small manual how to do it. Order new ones, don't reuse. Cut off 1-2 inches from the old connector cabling. At least in Germany I know those two kinds of connector outlets. > And yes, the room the cable is passing by has all kind or x-ray > machine. There's definitely problems with x-ray machines. Usually, those are connected by fiber optics (at least dental x-ray machines). You want to find a separate cabling way for your network, and also ensure that the power circuits are different between those machines and your network equipment. Ensure that shielding is properly passed along the complete cabling, including the patch cable from the wall outlet to your machine. Proper shielding is essential in such environments. We had one issue at a company running cooling generators and having unstable network. It was eventually resolved somehow but we think that the generators induced some non-harmonic distortion into the cabling of the complete building. I think it was resolved when they rechecked proper shielding on all cabling and machines. > I'll try to test it 100Mbit (limit the speed); just need to find out > how.

Re: [gentoo-user] Debian just voted in systemd for default init system in jessie
On Tue, Feb 18, 2014 at 10:36 AM, Andrew Savchenko birc...@gmail.com wrote: [...] Bugs are not equal. They differ in at least two dimensions: significance depending on the component affected and severity of the bug itself. I've never said that they don't have different significance, severity or scope. I said that all bugs are bugs (which is a tautology), and that you only need to fix them once to go on. Bugs in the critical system components are critical to the whole system. Yeah, that's why we have unit testing and QA teams and stable and unstable releases, etc. Every decent project has QA and unit tests one way or another. But the larger project is, the more bugs it has. And I do not want bugs in PID 1, that's why it should be small and sound, not bloated (even with some components split as separate binaries) and broken by design. Of course the larger a project is the *potential* number of bugs increases, but so what? With enough developers, users and testers, all bugs are *potentially* squashed. That's the important thing; you should not emasculate a project just to keep it simple under *your* definition of simple; have you looked at most of systemd code? It's actually pretty small and simple, and with well defined interfaces and boundaries. If Libreoffice or browser segfaults, some data may be lost and inconvenience created, but the system will continue to run. If PID 1 segfaults — everything is lost, you have a kernel panic. And the world will end? The same happens if the kernel has an error. Kernel has mature error correction infrastructure (Oops handling) and much wider community. And systemd has a *much* wider community than any other init system. So it can handle a larger code base. That's why critical components should be as simple and clean as possible. Like the kernel? You call that simple? Don't mix user space and kernel space, please. There are more secure by design micro kernels out there (like Hurd), but they're out of the scope of this discussion. I'm not mixing kernel/user space; I'm saying that critical components don't need to be simple; they need to be *reliable*. I'm sorry, but you are (IMO) wrong: critical components should be thoroughly tested and debugged, and have integrated unit testing, and a large enough group of volunteers to test new releases before they go into the general public. You're pointing to valid issues, but not to the whole picture. I just have a different point of view for the bigger picture. Critical components should _start_ from good design, sound modular architecture and _then_ with QA and testing. You're omitting the most important stuff, though. But systemd has a *good* design, a modular architecture (that's why it's splited in dozens of, you know, modules), and *besides* it has QA and testing. I'm not omitting nothing; I just don't share the same opinion as you as to what constitutes a good design. And this is debatable; with design, nothing is absolute. SysVinit code size is about 10 000 lines of code, OpenRC contains about 13 000 lines, systemd — about 200 000 lines. If you take into account the thousands of shell code that SysV and OpenRC need to fill the functionality of systemd, they use even more. If that code will fail, this wouldn't be critical at system level. Thus scope of fatal error is limited. Also in systemd, since most of its code is not critical (again; logind, datetimed, localed, etc., failing, has no impact whatsoever on the rest of the system). Even assuming systemd code is as mature as sysvinit or openrc (though I doubt this) you can calculate probabilities of segfaults yourself easily. I don't care about probabilities; I care about facts: FACT, I've been using systemd since 2010, in several machines, and I haven't had a single segfault. FACT: almost no bug report in systemd involves a segfault in PID 1. You need facts? Here is one for you (systemd-208): http://fly.osdn.org.ua/~mike/img/misc/systemd-segfault.jpg I've never said there was no segfaults; I said I had not a single one. Also, there are also segfaults for SysV, and for OpenRC, and for almost any other software out there. The important thing is the ratio of segfaults. Again, search for yourself in the case of PID 1 in systemd. And yeah, it will be larger than SysV, but SysV has, what, 40 years of existence? systemd has 4. Looks broken. Broken by design. The worst form of broken. By your opinion, not others. That is not just an opinion. There is a science and experience behind system's design. Yeah, what do you think about Greg Kroah-Hartman, Linus' right hand, or Keith Packard of X.org fame? None of them works for Red Hat; both of them know more about Unix and Linux than you and me together, and both of them promote systemd. I respect Greg for most of his work, but this doesn't mean he is an oracle we need to adhere to. But in FOSS reputation is not that important

With the lamp on unplug the UPS from the wall and see what happens. If the battery is dead it won't last all that long. Gave ~5 mins. So I let it charge for 24 hrs now it gives me 36 mins. Which is wierd; what happened to all that charge? I haven't had to use it for 6-7 mons. Isn't the unit supposed to stay topped-up? Well, assuming it was a 100 Watt incandescent that really draws 100 Watts, then that's probably 1/2 to 1/3 the draw of a typical desktop PC implying you would get 12-18 minutes before shutdown. (Really rough ideas - just numbers, etc. Don't take it too seriously.) These batteries have a limited lifetime and they need to be charged up if they haven't been used in a while. From the APC Forums an APC representative posted the following. Note #3: [QUOTE] Most APC batteries should last three to five years. Below are some guidelines to ensure optimum life expectancy: ***Some APC Back UPS models may have a shorter battery life expectancy. Please reference the user's manual of your APC Back UPS to determine the exact battery life expectancy. 1. Make sure that you keep your APC UPS in a cool, dry location with plenty of ventilation. Ideally, the temperature where your UPS is kept should not exceed 75° F (24° C). Also, for ventilation purposes, leave roughly one to two inches on each side for proper airflow. 2. Only perform runtime calibrations on your UPS one or two times a year, if necessary. Some of our customers want to check their systems to verify that their runtime is sufficient. However, consistently performing these calibrations can significantly decrease the life expectancy of your APC battery. 3. Do not store APC batteries for extended periods of time. New batteries can be stored for 6 to 12 months. After this period, the battery should be used or it will lose a great deal of its charge. It is not advisable to store batteries that have already been in use. 4. Do not exceed 80 percent of a UPS unit’s rated capacity due to the reduction in run time. When you increase your load, your runtime lessens. In the event of a power failure, a UPS loaded to full capacity will drain and discharge it’s battery quickly and will lessen the life expectancy. [/QUOTE] Another thing: When I do the remove-the-usb-cable test I don't see the communication lost error in apcupsd.events until I switch the dial-up off and on quickly! In the conf file I have DEVICE: /dev/ttyS[0-3] because the default, /dev/ttyS0, locks out the modem. But why does the UPS need to know about serial ports? It connects by this funny RJ-45/USB cable. I wonder does the manufacturer assume the serial port won't be used? Strange stuff but above my pay grade... - Mark
Re: [gentoo-user] /dev/input/mouse0 Doesn't Exist
If they worked previously, they are probably compiled into the kernel. I find this is a mistake unless you have a specific reason for doing so - being able to remove/add modules helps track down weird problems like this, and some things just work best as a module. I take it that it is a usb wireless mouse ? (coz of the batteries). If so, monitor the syslog while adding or removing the usb plug. If its recognised, you will see messages. I doubt the batteries are the problem as with a wireless mouse, its the base unit that when plugged in will cause the /dev node to be created and you dont have them. If I am wrong about the mouse, exactly what type of mouse and ports are you trying to use (as you have probably gathered, this has a bearing on whats happening) BillK On Wed, 2005-09-07 at 10:00 -0700, Drew Tomlinson wrote: On 9/6/2005 9:53 PM W.Kenworthy wrote: use lsmod to get the module list.

I find this is a mistake unless you have a specific reason for doing so - being able to remove/add modules helps track down weird problems like I have no specific reason. I will note this for my next kernel build. this, and some things just work best as a module. I take it that it is a usb wireless mouse ? (coz of the batteries). If so, monitor the syslog while adding or removing the usb plug. If its recognised, you will see messages. I doubt the batteries are the problem as with a wireless mouse, its the base unit that when plugged in will cause the /dev node to be created and you dont have them. Kind of. It's a Logitech wireless mouse/keyboard combo. One of the outputs (I think it's the mouse) is USB but I have it plugged into one of those converter thingys so it is essentially a PS/2 mouse. The other output is a standard PS/2 jack. But your suggestion prompted me to unplug/plug the mouse in. Must have been loose because after doing so, I had /dev/input/mouse0 and after a reboot, X windows starts and the mouse works fine. Thanks for all of your help! Drew If I am wrong about the mouse, exactly what type of mouse and ports are you trying to use (as you have probably gathered, this has a bearing on whats happening) BillK On Wed, 2005-09-07 at 10:00 -0700, Drew Tomlinson wrote: On 9/6/2005 9:53 PM W.Kenworthy wrote: use lsmod to get the module list.

No upgrade of gdm, but a re-build as it changed USE-flags (-consolekit systemd). What does systemctl --all --full says, which units are in red? # systemctl --all --full | grep erro auditd.service error inactive dead auditd.service plymouth-quit-wait.service error inactive dead plymouth-quit-wait.service plymouth-start.service error inactive dead plymouth-start.service syslog.service error inactive dead syslog.service # systemctl --all --full | grep fail gdm.service loaded failed failedGnome Display Manager I dont't have plymouth or sys-process/audit ... nothing pulled that in. sshd.service, ssh@.service, systemd-update-utmp-runlevel.service, and systemd-update-utmp-shutdown.service have auditd.service in their After= field; several others have plymouth services. After= is just for ordering of units, is not a requirement; systemd detects that auditd.service doesn't exists, and it starts the units that have it in ther After= field anyway. To make a unit depend on another, you need Require=. You can mask the services you don't have by creating a soft link to /dev/null: # ll /etc/systemd/system/rc-local.service lrwxrwxrwx 1 root root 9 Aug 16 13:51 /etc/systemd/system/rc-local.service - /dev/null It cleans up the output of systemctl --full --all. And lastly, how did you set gdm as your display manager? Do you have: # ls -l /etc/systemd/system/display-manager.service lrwxrwxrwx 1 root root 37 Dec 6 00:40 /etc/systemd/system/display-manager.service - /usr/lib64/systemd/system/gdm.service ? Right now it links to xdm, but I had it the way you posted and tested that. When I test, I switch to a text console: systemctl stop xdm systemctl start gdm Well, I have no idea why your gdm is not letting you log in; obviously it's related to polkit (since it started when you changed from consolekit to polkit), but nothing in your config seems to differ from mine. It is not impossible that somehow the configuration files of the gdm user got messed up when the change happened. I don't know how this could happen, but as a hail Mary you could delete /var/lib/gdm, and reemerge it so it gets a clean install. Also, you have USE=pam for polkit, right? And could you post the output from journalctl -b /usr/lib/polkit-1/polkitd? Regards. -- Canek Peláez Valdés Posgrado en Ciencia e Ingeniería de la Computación Universidad Nacional Autónoma de México

The low results for the SSD are because of the lower-spec hardware of the rest of the system. Speed is always determined by the slowest part. In this case, the difference is very noticable.
