Re: ZFS Snaphost Hardware RAID
2009/11/16 Johan Hendriks jo...@double-l.nl Hello all. I plan to set up backup server with 24x1Tb HDD and use ZFS with FreeBSD-8.0 on it. I prefare to have ZFS only system but as I see there is no any easy way to do so. I would like to use ZFS snapshots - is I undestand right what snaphots work OVER ZFS raidz\storage? So I can`t use hardware RAID and must make a raidz? I would love to head any other suggestion about using FreeBSD with ZFS as backup server. -- Best regards, Proskurin Kirill An option is reading this thread on the FreeBSD forums. http://forums.freebsd.org/showthread.php?t=3689 regards, Johan Hendriks ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org zfs works fine with hardware raid controllers, it just means the disk setup can be a little more complicated, and needs to be thought about a bit more. Personally I would JBOD all the drives apart from the system drives which I would create a mirror for. With this setup you utilize all the best features of the hardware and software. System zpool with hardware mirror means you are less likely to get issues booting as bios will see the virtal device exported by the raid card and wont have to alter the boot drive if one of your system drives dies. Just give the system zpool on dev backup zpool: raidz2 ( group into vdevs of 8 drives ). If you export the drives from the hardware raid as a jbod and get zfs to do all the raid stuff, you will enjoy more funky raid configs, and if you have to rebuild a drive it will odds on be much quicker as you only have to do allocated blocks as opposed to full block rebuild of the entire drive as the raid controller would do. Also using the raid card rather than straight scsi you might get benefits from the raid cache, if its cpu is quick enough. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Lockup problems with USB disks
I have a USB hard drive. Whenever I open two programs which utilise the USB hard drive simultaneously, these programs, i assume when they attempt to write to the hard drive lock up due to what i suspect must be some issue with the USB driver and perhaps a deadlock involving multiple concurrent accesses to the drive. When they attempt to access the drive the programs can lock up for several minutes before being unblocked. When only one program is using the drive this behaviour does not seem to occur. It seems most likely that this is a USB level problem involving the USB drivers. I am using FreeBSD 7.1. It is annoying behaviour to say the least and I wonder what can be done about it, and if this issue is being addressed, perhaps in the recent redesign of the USB code. It seems to be a pretty consistent issue, happening with multiple installs of FreeBSD and different drives.

Have not tried to put this disk into a windows/another box...
I don't know why other than it has apparently been marked
with an fstype (sysid) of 6 at some time. Maybe something
started and went long enough to muck with the slice table but
then did nothing else.
Anyway, if you can mount, read and write it OK, I would not
worry too much. If you plan to wipe and it for a new install
it should not be a problem.

If a sector fails, it is replaced by one of the spares by the firmware. If you see a non-zero Reallocated_Sector_Ct, it means that the drive has run out of spares. This is bad news. Surely it's the other way around - if you see a value of zero in the value column the drive has run out of spare sectors and it's time to RMA the drive? I was talking about the _RAW_VALUE column. There seems to be some differences in interpretation between vendors as to what the VALUE column means. Most of the advice I've seen over the years says to look at the RAW_VALUE. See http://en.wikipedia.org/wiki/S.M.A.R.T. as well. Mmm, but as that article - which really only mentions the 'normalised' values smartctl presents in passing - points out, there can be quite a lot of variation between different manufacturers as to what RAW_VALUE actually represents for various attributes, whereas the usage of VALUE WORST THRESH values is much more consistent, and what the vendor is actually presenting as the SMART good/fair/fail analysis to the world. For instance, I've got two Fujitsu 5400rpm 2.5 drives in two laptops, one MHV2040AH with near 19,000 hours on it, and a much newer MHV2120AH, 40 and 120GB respectively. Nice quiet low-power laptop drives, fwiw. Both show as (more recently) being in the smartctl database, and both show _exactly_ the same values for this one: 5 Reallocated_Sector_Ct 0x0033 100 100 024Pre-fail Always - 8589934592000 Now if that were a number of 512-byte sectors, it'd be 4096000 GB! :) but both drives are 100% ok, as the VALUE / WORST figures show. From what I've seen the 'raw' column appears to count the number of sectors the drive has remapped using the spares buffer. If it gets into the hundreds it's probably time to think about RMA'ing the drive Yes, the raw value is the number of sectors allocated from the spares. I originally thought it was the number of reallocations _beyond_ the spares. That's a misunderstanding on my part. Again, may depend on the drive make/model. With the same make/model you can of course usefully compare raw values, but be careful about drawing inferences for different drives, or you may be RMA'ing needlessly .. Nevertheless this attribute (along with several) is marked on the Wikipedia page for smart as a Potential indicator of imminent electromechanical failure. You can find the same attributes marked as critical when perusing mailing list archives. For me, my data is worth much more than the harddisk it is on. Some of it is literally irreplacable. So my policy is to go look for a replacement harddisk as soon as the RAW_VALUEs of any of these critical indicators start going up from zero. And store any data at least on two harddisks, whether in a mirror or in a cron+rsync setup. That'd be the case for the disks you tend to use. I was first going to reply to Bruce's message when I spotted yours, but you've dropped the last bit of his quote, that I was about to wholeheartedly agree with :) : If it gets into the hundreds it's probably time to think about RMA'ing : the drive - if you trust that the 'raw' column is reporting what you : think it is (you should really only base your decision on the value, : worst and threshold columns). cheers, Ian ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

pf in FreeBSD 8.0-RCx
Hello All, There seems to be an issue with pf (at startup/boot time) where I get an error message about no IP address being associated with an interface. The only way I can get pf to load the rule set is to load it at the command line by using pfctl -f /etc/pf.conf. I have tried changing the startup order of pf so that it loads after all of the networking interfaces are brought up (including running the ppp daemon first to establish tun0) to no avail. I saw on the list that others have been experiencing a similar issue. Obviously, I would like to have a fix for this because if I have to reboot my box from a distant location, I am left with a wide open machine until I can login and reload the pf ruleset. What changed with pf since 7.2? Thanks, Matt ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Re: hdd voltage
Thank you guys for the interest you bring solving my issue! Actualy I noticed one thing for sure: I have to hdd-s in my PC, an 80GB Seagate ATA (the o.s. boot hdd) and one 1T Seagate SATA (only for storage), there were no problems when I used just the 80GB neither with the 1T, I noticed only that I'm getting thouse reboots when I start to copy about more than 4-5GB from the 1T hdd to my laptop (on ftp). Maybe the hdd was too warm after copying that amount of data? Oh...I'm drunk or something but I just noticed that my 1T was not unmounted properly last week and I was doing only fsck with the disk mounted so nothing was modified to the file system, now I've done an fsck -yf to the 1T (unmounted)...I got some blocks (about 300) reapaired. Maybe this produces the reboots, what do you think so? I also done now an smartctl -l scttemp /dev/ad4 and I got the following result: 862009-11-17 19:4045 ** 872009-11-17 19:4145 ** 882009-11-17 19:4246 *** 892009-11-17 19:4345 ** 902009-11-17 19:4445 ** 912009-11-17 19:4546 *** 922009-11-17 19:4645 ** 932009-11-17 19:4746 *** .....( 4 skipped)... *** 982009-11-17 19:5246 *** 992009-11-17 19:5347 49 Celsius was the top of the tempature for this hdd, I think its normal.

A very good-quality power supply with a thermally activated circuit breaker might tolerate a 250% overload for 20 seconds to a minute, but anything with a fuse is likely to blow in some tens of milliseconds. :-) There are some widely used standards for computer power supplies; almost all modern machines want ATX12V which is used by Intel P4s, Core, etc and AMD Athlon, Athon64 platforms. Multicore boxes commonly want another extension to the base ATX standard called EPS12V; both are well-documented here: http://en.wikipedia.org/wiki/ATX The other major standard in 80-plus certification, which is linked to Energy Star ratings; if you discount the branding, they still perform functional tests of PSUs at 20%, 50% and 100% of rated load, and confirm that the PSU isn't wasting excessive amounts of power. Saving 20-30 watts over time justifies the cost of a more expensive PSU, and it doesn't hurt that the machine doesn't have to deal with the extra thermal load. For example: http://www.80plus.org/manu/psu/psu_reports/CORSAIR_CMPSU-650HX_ECOS%201632_650W_Report.pdf Any new PSU which isn't 80-plus certified is pretty likely to be unable to run at 100% of rated load without failing. Additionally, are you sure your service power is good? Even the best power supply will fail if you're not getting 120V/60H at the outlet (or whatever voltage/freq you're supposed to get in your part of the world). This is also a good point. If you know what you're doing and have a multimeter, you can check your AC line and look for various issues like voltage sag under load, current leakage to ground, etc. Failing that, something like this Kill-A-Watt meter is quite handy: http://www.newegg.com/Product/Product.aspx?Item=N82E16882715001 ...although, obviously, one would want to obtain a unit intended for the local region's electrical standards if you are not in NA.

[...] But Edison's greatest achievement came in 1879, when he invented the electric company. Edison's design was a brilliant adaptation of the simple electrical circuit: the electric company sends electricity through a wire to a customer, then immediately gets the electricity back through another wire, then (this is the brilliant part) sends it right back to the customer again. This means that an electric company can sell a customer the same batch of electricity thousands of times a day and never get caught, since very few customers take the time to examine their electricity closely. In fact the last year any new electricity was generated in the United States was 1937; the electric companies have been merely re-selling it ever since, which is why they have so much free time to apply for rate increases. [...] Here is a simple experiment that will teach you an important electrical lesson: On a cool, dry day, scuff your feet along a carpet, then reach your hand into a friend's mouth and touch one of his dental fillings. Did you notice how your friend twitched violently and cried out in pain? This teaches us that electricity can be a very powerful force, but we must never use it to hurt others unless we need to learn an important electrical lesson. It also teaches us how an electrical circuit works. When you scuffed your feet, you picked up batches of electrons, which are very small objects that carpet manufacturers weave into carpets so they will attract dirt. The electrons travel through your bloodstream and collect in your finger, where they form a spark that leaps to your friend's filling, then travels down to his feet and back into the carpet, thus completing the circuit. -- Dave Barry: The Taming Of The Screw And: Yes, I know it's OT, but it makes electricity problems look easier because you can now easily understand them. :-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Wester Digital 'deep recovery cycle' and gstripe?

Re: flashplugin
I never had tried to install Linux flash. I did install Windows flash under Firefox on Wine and it worked. I found that the freebsd port for Wine would not work but if I downloaded the source from WineHQ and compiled it would work fine, however, i tried a more recent version of Wine which did not compile right on FreeBSD, my current properly compiled wine version is, 1.1.7. You can try the most recent version of Wine and see if tht works, if not you can try 1.1.7 which worked well for me.

Re: jail - beginner questions
No, I think you added the '/' before 'etc', which isn't in the web page. Gotcha. Is the problem perhaps in your /etc/rc.d/vm1 script? Normally you would use /etc/rc.d/jail. Yes, I'm. Sorry - it was a typo. I used this: /etc/rc.d/jail start vm1 Are those addresses already assigned on the host? Was the jail perhaps already running? My computer is a windows machine, with address 192.168.0.X Then the FreeBSD host is actually a guest os running in wvmare. It has address 192.168.37.133 And finally, the vm1 jail should have 192.168.0.11 I don't know why 192.168.0.11 is not working for the jail. Anyway, if I change the jail's address to 192.168.10.11 then /etc/rc.d/jail start vm1 Starting jails: vm1.localdomain. Now the next question: how can I access the hosted (jailed) OS? I know it is a dumb question, but I have no idea. I would like to: a.) run sshd in the jail b.) login from the host to the jailed (hosted) OS c.) install programs on the jail, configure them and finally d.) use NATD to divert some pacakges from the host to the jail and back Probably this is what everybody does, so if you could point me to a tutorial or something, I would appriciate it.

Polling probably works better with a single CPU, compared with doing service handling threads per interface, which can do better on SMP boxes. However, the main consideration is probably whether your NICs know how to do interrupt mitigation-- if they do, using that is probably better than using device polling, at least for low-to- moderate network load. Polling handles high load better; it wastes a fair amount of CPU under no to low network load. The base recommendation is to set HZ to 1000. If your CPU is having problems with that, try 250 or 500 HZ.

Both show as (more recently) being in the smartctl database, and both show _exactly_ the same values for this one: 5 Reallocated_Sector_Ct 0x0033 100 100 024Pre-fail Always - 8589934592000 Now if that were a number of 512-byte sectors, it'd be 4096000 GB! :) but both drives are 100% ok, as the VALUE / WORST figures show. I wouldn't conclude that the drives were 100% OK from that line, although they *might* be; I'd conclude that the drives aren't implementing this SMART field correctly in their firmware. Are you using the latest version of smartctl-- updates to that can sometimes better interpret vendor-specific odditities. Hi Chuck, Well, _Fujitsu_ reckon they're 100% OK on THAT attribute (100 100 024), which is the point I (and Bruce, I think) was trying to make, along with perhaps a gentle don't believe everything you read on Wikipedia :) The smartctl program is not definitive for RAW_VALUE attributes; the manufacturer is. Some raw values are manufacturer-specific, like this one, and the smartctl author likely concentrates on the lowest hanging fruit; its database is already huge. This one is larger than 32 bits, possibly a mis-byte-ordered 48- or 64-bit value? If the two drives showed different values I'd pursue trying different byte orderings. And no, this certainly wouldn't be the latest smartctl; to compare the 120G drive I installed (last night) smartmontools on a 7.0 system that's soon to be upgraded to 7-STABLE, so using a 7.0-RELEASE ports tree with smartctl 5.37, which shows '009 Power_On_Seconds' as the only odd value for this make/model, from smartctl -P show /dev/ad0 cheers, Ian ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
Do permissions take time to take effect?
Hello, I wanted to create a shared directory writable by all users. When it initially failed, I assumed there may be a blanket ban on writing to directories owned by root. Today, I was able to write to the root-owned Share directory. However, when I re-created the directory owned by a special-purpose Share user, I ran into the same problem again. $ cd $ pwd /home/james $ cd /home/Share $ ls -la total 4 drwxrwxr-x 2 root users 512 Nov 14 09:39 . drwxr-xr-x 5 root wheel 512 Nov 14 09:39 .. $ grep users /etc/group users:*:100:james,backup $ cat test.txt What? now it worked? $ ls test.txt $ rm test.txt ***After creating a special Share user*** $ cd /home/Share $ ls -la total 4 drwxrwxr-x 2 Share Share 512 Nov 17 21:04 . drwxr-xr-x 5 root wheel 512 Nov 17 21:04 .. $ cat test.txt cannot create test.txt: Permission denied $ grep Share /etc/group Share:*:1003:james,backup $ Incidentally, I had another reason for creating a special-purpose Share user: I am exporting /home to Debian (Linux) clients.

It has address 192.168.37.133 And finally, the vm1 jail should have 192.168.0.11 I don't know why 192.168.0.11 is not working for the jail. Anyway, if I change the jail's address to 192.168.10.11 then /etc/rc.d/jail start vm1 Starting jails: vm1.localdomain. The address 192.168.0.11 must be assigned to a interface in the host FreeBSD. You can do it before starting the jail, or when the jail is being started. To assign the address before starting the jail do somthing like this: # ifconfig lnc0 alias 192.168.0.11/24 where lnc0 is the name of nic in the host FreeBSD And you can add to /etc/rc.conf: ifconfig_lnc0_alias0=inet 192.168.0.11/24 to assign the address then the host FreeBSD is booting. To assing the address when the jail is being started just add to /etc/rc.conf this: jail_vm1_interface=lnc0 This way is preferred. Now the next question: how can I access the hosted (jailed) OS? I know it is a dumb question, but I have no idea. I would like to: a.) run sshd in the jail b.) login from the host to the jailed (hosted) OS c.) install programs on the jail, configure them and finally d.) use NATD to divert some pacakges from the host to the jail and back b.) 1. get the jails list: # jls JID IP Address Hostname Path 9 192.168.64.14 mx1.loc /store/jail/mx1 8 192.168.64.25 nslst.loc /store/jail/nslst 2. select required jail by JID, for example 9 for mx1.loc and do: # jexec 9 tcsh 3. you're in a.) Login inside the jail. Now add to /etc/rc.conf sshd_enable=YES and execute: # /etc/rc.d/sshd start c.) When you're inside the jail you can install software like in the host system. You can use the pkg_add or the ports system. d.) It requires to use firewall either ipfw or pf. For example you can add to your /etc/pf.conf: nat on lnc0 from 192.168.0.11 to any - 192.168.37.133 But the firewall requires more lines then this one to work correcly with all network traffic. And you have to know exactly what you want to get for using it. Probably this is what everybody does, so if you could point me to a tutorial or something, I would appriciate it.
