Epic5-0.3.1 ruby support and FreeBSD AMD64 problem
I'm the port maintainer for irc/epic4 and irc/epic5 and try to liason with the developers as much as possible. I've received a request from the Epic developers that I can't really help with and I'm wondering if someone would be willing to be able to lend them a hand. Epic5-0.3.1 includes optional ruby support. When ruby support is compiled in on an AMD64 box attempting to use gdb on it spontainiously reboots the box, no panic, no hang, just a hard reset. The problem has been verified to occur on 5-STABLE and 6-STABLE on multiple machines. It does not occur if the gdb from devel/gdb6 is used. At the moment I'm dealing with the situation by keeping the port at 5.0.2.0 but I'm getting more and more requests to get 0.3.1 into the tree. Given the nature of the problem doing so at this point means either not having the ruby support in the port or marking it broken for AMD64, neither of which are particularly attractive. Any level of help would be appreciated, whether it's just a 'here's what I would look for first all the way up to digging into some code. I'd rather not post email addresses to the list but if a kind soul wishes to get in contact with the epic team I can give contact info out privately. Another (possibly useful) data point that occurs to me is that it hasn't been tested on any sort of 64 bit linux at all, so it's really unknown if this is FBSD specific. -- Thanks, Josh Paetzel ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]

Why not test for both conditions? I.e. - if ruby support is included (you did say it was optional) AND if you're on amd64, then mark the port as broken? Better yet, since using devel/gdb6 seems to fix the problem, use devel/gdb6 under those conditions. Or - to keep it simple - always use devel/gdb6. Note that getting this problem fixed won't meean you can ignore it. If you want to avoid building with the workaround (whatever that may be) on amd64 after the fix has been committed, you'll have to check the OS version, and optionally build with the workaround if someone is installing the fix on an earlier version of FreeBSD. mike You're right. The workaround could be more sophisticated. Thanks for pointing that out. I guess my perspective is that this issue is being caused by a problem in the code for epic, not a bug in FBSD. From the wording of your email I sort of get the impression you are thinking along the lines of it being a FreeBSD bug? My main plea is for someone familiar with FBSD to volunteer to give these guys a hand in tracking this down. :) -- Thanks, Josh Paetzel ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]

Could someone point me to a good performance tuning document for bge(4) handeled NICs, under SMP kernel or at all? Thanks in advance! Vladimir So you have 2 gig-E and 4 100tx interfaces on the same PCI bus? If so you're going to run into bus saturation long before you're able to max out the throughput on the NICs. Which isn't to say that 200 kBps isn't a problem, but perhaps you are dealing with a bad cable or switchport. -- Thanks, Josh Paetzel ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]

One of the AIC's is connected to a SCA Backplane that holds 4 disks. Now before even having a chance to see if FreeBSD-SMP works with this box, I didn't manage to install FreeBSD (4.1) correctly. Well, installation seems to go well in any attempt: - Floppy boots, Kernel finds all ahc's and disks - Installation seems to succeed (Partitioning, installation, etc) But then, the machine won't boot. It seems to happen, that the MBR of the target device (da0, which is the first disk on the second controller, channel A of internal AIC's) is found, but the next stage of the bootstrapping process cannot be found. I played also around using boot0 and installing on other disks, this is like what I got: Standard MBR and System on da0: - Missing operating system boot0 MBR and System on da0:- F1 - *beep* (nothing else) boot0 MBR (and old System) on da0, standard MBR and System on da1: booting from da0: F1 - *beep*, F5 (disk2) - Missing operating system booting from da1: - Missing operating system So it seems no boot-block after the MBR can be found. I tried: - installing and booting from different disks on internal ahc - disabling some of the controllers - installing and booting from a disk on the 2940, as well while disabling the others It all had no effect. All adaptec's BIOS has Disks 1GB and INT13 enabled (of course the BIOS itself is enabled, too) Previously Solaris 7/x86 was running on this machine, there were no such problems, but we don't really want to run Solaris... :-} Any clue ? If it is worth anything, I tried installing on a poweredge 2450 once and to make a long story short couldn't get the onboard RAID to work or the SMP to work.

The SMB sessions would randomly change speed, and telnet sessions would suffer from occasional hesitation (this is on a Dual PIII-700 MHz machine with 1 Gb of RAM, which is currently very lightly loaded). I managed to track the problem down to the duplex settings on both the Ethernet cards (AT-2500 TX, Realtek 8139 based, AFAIK) and the 10/100 Switch. Forcing both the cards and the switch to particular settings cured the problem, and lead to a massive performance increase. FTP seems to be particularly badly affected by the constant collisions (causing backoff). The problem can be tricky to find as the switch wasn't perceptably showing collisions on the collision LED, but viewing the switch stats showed a different story! I've noticed similar problems with Linux and certain cards (it was a while ago). John Vinters [EMAIL PROTECTED] Well, I am seeing dismal ftp performance on my 4.x boxes. I have a network of 4 machines, three of which are running -STABLE from Nov 22. The other machine is running NetBSD 1.5.2 Release. One of the FreeBSD machines has a base 10 cards in it and has reasonable performace with ftp transfer rates around 1.1Megs/sec. The NetBSD machine is a sparcstation 10 with an onboard intel base 10 adapter, and it too sees reasonable ftp performance. The other two -STABLE boxes have 100tx cards in them. One is a Linksys LNE100TX, and the other is an intel Pro 10/100B/100+. The hub for this network is an 8 port SOHOware autosensing affair. Both of the 100 cards auto-negotiate to 100tx half-duplex. I can get appoximately 1.5Megs/sec out of them using ftp. I have tried swapping cables, swapping ports, and replacing the hub with a crossover cable and manually configuring the cards for either full or half duplex operation. None of these steps makes any difference at all. I can reliably duplicate my transfer speeds on a 600 meg file with a std. deviation of less than a half a second no matter what network configuration I use. My next step will be to try some different NICs, but I don't have anything here that is 100tx based to swap with. I have gotten proper transfer rates out of these machines in the past, but I don't remember if the network cards have changed since then. I rarely move large files around at all, and so only looked into this as a curiosity when seeing this thread. I also intend to try some NFS mounts out to see if this is a protocol issue or not.

Re: Discussion on the future of floppies in 5.x and 6.x
There are several documents linked off of http://www.freebsd.org/releng that describe how to build a release. It's not nearly as arcane of a process as it used to be 5 years ago. The biggest barrier to entry is probably disk space. You'll need a good 5GB free to hold the CVS repo, chroot environment, and resulting bits. Well, I've got the CVS repo, though boy, has *THAT* ever grown since I built this system; I had to trim it down to only src and ports, and even so: /dev/da1s1e 2032623 1769089 10092595%/usr/cvs Of course, I left out the ports and docs parts of the release last time I tried (which was in fact about 5 years ago ;), though I had all kinda of troubles with parts of THAT, too. But still, I don't have even a tenth that much hard drive space around. Yes, to build the floppies you need to build most of the release, but once you've built the release, you can back-step and rebuild the floppies at will. And building the whole release is quite an ordeal on a Pentium Pro :) Still, I'm willing to donate some time and brain to the problem, since apparently I kinda care about it. It seems to me that the probing problem above is the biggest problem from a real coding POV; the rest is mostly just a whole heck of a lot of implementation, and inconvenience from the usability standpoint. That's a breaking point. I'll donate the disk space and CPU time if you want to run with this. I have an interest in keeping floppies around, but not much ability to help out.

If you are doing a fully scripted install you may be better off just using a dedicated shell script to format your disks and mount them and then use the various *-install.sh scripts from the release distributions to install the code. You could still do this via sysinstall by sticking your shell script in /stand in the MFS root and having your sysinstall script just run that script. You might want to build a custom mfsroot to add some more useful tools though. I really think sysinstall needs to support a disk backdoor whereby the user can either manually partition disks and then mount them at /mnt (or have a script do it), and tell sysinstall to just skip the disk stuff and assume /mnt is mounted. David, I second the ditching sysinstall for a shell script idea. A shell script that replaces sysinstall is nearly as short as the install.cfg and a lot easier to figure out.

FWIW, sysinstall(8) is a good starter tool and it has a lot of the
information that you need in order to complete an install (especially
if you're doing it from scratch), but the amount of effort for using
sysinstall(8)'s install.cfg, etc has the greater potential to change
in the future when compared with a shell scripted method which is less
likely to change; granted gpart vs fdisk is in transition, but the
number of steps and the simplicity required to get everything up and

I'd be happy to share my custom script if desired as well to provide

One of my main issues with using sysinstall comes from an intersection of it's
lack of documentation, and the way it can arbitrarily change over time. For
instance, this week I was working on an install for a number of machines that
had to be imaged with an early 7.x version of FreeBSD, and were specified to
be installed with distSet${OBFUSICATED} In order to determine what
distSet${OBFUSICATED} installs on 7.${EARLY} involves either installing a
system via sysinstall and noting what it installs, or reading the source code.
Where this becomes an issue is sysinstall changes over time,
distSet${OBFUSICATED} is not necessarily the same between 7.${EARLY} and say
8.0. Since there is no documentation you either end up tracking the changes
to sysinstall, or sorting it out at upgrade time.
I'd also like to mention John saying you can build a custom mfsroot to use
additional tools during install...I go a different tack on this. I'm a huge
fan of python, and like to use it for installers. Rather than build a custom
mfsroot with python what I prefer to do is build a chroot that the target
machine boots diskless off. Then I chroot into that directory and install
whatever tools I want using ports/packages. I find that getting FreeBSD to
boot diskless is so easy that I've had it accidentally happen more than once
when I wanted something else to happen. Installing ports in a chroot is also
pretty trivial. Building a custom mfsroot has a bit of a learning curve with
a fairly expensive trial and error penalty.
At any rate. There are a lot of compelling reasons to not use sysinstall for
automated installs. And while there are compelling reasons to use sysinstall
for this task, most of them involve things like I'm a masochist. or It was
there so I thought I'd use it.

txt-sysinstall scrapped
It's been incredibly busy for us in iXsystems land, with a lot of irons in the fire. One of the many things we've been working on is a new installer. Several months ago pc-sysinstall was imported into HEAD from the PC-BSD project. pc-sysinstall is a fine tool, and very useful as the backend for doing scripted installs. If you're using scripted sysinstall I recommend you check it out, it's a lot easier to use and configure than sysinstall, the documentation is much better, and reasonable requests for functionality can and will be brought in. This is all fine and good, but without a front end to generate the config files pc-sysinstall needs it's not much use to an end user for doing installs. We (and by we I mean the forces at iXsystems) have been working on txt- sysinstall, which is a front end for pc-sysinstall using curses and dialog to generate a pc-sysinstall config file from user input. What we've encountered is that doing disk configuration in dialog isn't possible, and we started down the road of using cursesbut we already have a curses and dialog based installer, and wouldn't it be neat if we could use the disk configuration tool we are writing for FreeNAS, too bad it's a web app. But if the installer just launched a web server. Ok, wait a minute, that couldn't work...how would you configure networking? Oh wait, that's already solved in FreeNAS, before you access the system you use a console/CLI app to configure the network. Ok, but people do installs over serial portsoh wait, you could run lynx from the console too... We quickly realized that the objections we could come up with were easily overcome, and the more we talked to people here at MeetBSD the more we realized it was a viable (and good) idea. People quickly came up with improvements. This gets us the best of both worlds. Want a super fancy GUI installer, just hit the box with firefox or whatever from a full desktop, want a text interface that's simple, need low bandwidth, running over a serial port, use the embedded lynx browser. Installing in a remote vm/cloud, just configure the ip and hit it with a browser (yes, we're dreaming up ways to do it over ssl and such) I'll do a better write-up very soon, I'm pretty tired now and have a long weekend looming, but just wanted to get the word out. Just to give credit where credit is due, this all started with Warner Losh saying, Can you listen to a crazy idea I had? It didn't take long to realize that it wasn't crazy, it was a stroke of genius. Secondary props go to Philip Paeps and Kris Moore for implementation details, Matt Olander for recognizing the benefits and approving the change in focus, John Hixson for the priceless look on his face when he realized we were serious about changing (He's done the bulk of the work on txt-sysinstall) the random NetBSD user here at MeetBSD (sorry I don't know his name) who said it was a horrible idea because it would bloat the installer way too much (I'm still laughing at that, he was saying something about floppies too, I guess we're locking out people using 386's or something.) and quite a few other people who are too countless to mention but offered random advice or encouragement. -- Thanks, Josh Paetzel FreeBSD -- The power to serve signature.asc Description: This is a digitally signed message part.

Initially the card is not seen at all by the driver, however pciconf
shows us why that is.

vendor = 'LSI Logic / Symbios Logic'
device = 'MegaRAID SAS 9240'

It seems on other models of LSI SAS2008 the chip device ID is 0x0072,
however for some reason this card has 0x0073. So I patched the mps(4)
driver and recompiled.

From this point I'm stuck on what to try next, google does not provide
any answers for this situation. Does any one have any advice or ideas
as
to why this is not working?
I am able to provide ssh access to the server if any one wants to log
on and have a look at it.
In looking at the specs, that card supports RAID-5 and RAID-50. That
means
it isn't a SAS card supported by mps(4), but rather a MegaRAID card.
This is Megaraid card. And it should not be supported by mps. Again, Just
adding 0x73 in your pci list in mfi driver will not solve your problem.
Please Check with Megaraid FreeBSD drivers.
~ Kashyap
It should be supported by mfi(4). Try adding the PCI ID to that
driver and see if that works. Or you can grab the driver from the
head_mfi branch, it looks like it already supports that card. Here's
the
mfi_pci.c file, you can see the PCI ID in there:

The FreeBSD mfi will not support that card. The LSI mfi will, but they
aren't done with it as far as I know (spoke with their driver team a few
weeks ago)
The slightly riskier option is to flash the card with IR firmware for a
9211, the MegaRAID component of that card is purely software and the
underlying hardware is supported by mps. Of course a firmware flash
gone bad will turn it into an expensive chunk of fiberglass, but if you
google around you'll find people who have done so successfully.
