xfs_repair doesn't fix sb versionnum missing attr
by C Linus Hicks 12 Feb '10

12 Feb '10

I run: xfs_check /dev/sdc10 And it reports: sb versionnum missing attr bit 10 Then I run: xfs_repair /dev/sdc10 And it reports output from 7 phases and "done". Again I run: xfs_check /dev/sdc10 And it reports: sb versionnum missing attr bit 10 Is this how it's supposed to work? Thanks for any help. Linus

A server at work today appeared unresponsive to all network traffic. The machine in question doesn't have a k/v/m terminal; it's configured to use a serial console. So I connected to the serial console and got /etc/issue (with all the \char sequences properly expanded). At the login: prompt I typed root and pressed Enter. Several seconds went by before the Password: prompt was displayed. I typed the password and soon saw Login timed out after 60 seconds At which point /etc/issue and the login: prompt reappeared. Later investigation revealed the load average was hovering around 100, so it's unlikely the machine would be able to process the username and password in under a minute. I'm trying to figure out if it's possible to lengthen that timeout value from 60 to, say, 180. This isn't the first time I've wanted to kill a runaway process and been unable to get a console because of that timeout. -- Paul Heinlein <> heinlein(a)madboa.com <> http://www.madboa.com/

Slightly broken audio on USB headset?
by tony＠softins.clara.co.uk 12 Feb '10

12 Feb '10

I have a Logitech USB headset which I have used very successfully on Windows for a long time. The other day I thought I would try it out on my CentOS 5 server, which doesn't have its own sound hardware (HP ML110). On plugging it in, all the required modules magically got loaded, and the "play" command would play sound files as expected. However, at all times when playing a sound file there was a ticking sound two or three times a second, as if there were regular discontinuities in the audio. Apart from the ticking, the sound quality was fine. Can anyone suggest what I should look at to start diagnosing and fixing this issue? Thanks Tony -- Tony Mountifield Work: tony(a)softins.co.uk - http://www.softins.co.uk Play: tony(a)mountifield.org - http://tony.mountifield.org

what causes CUPS to dis-enable a printer?
by Paul Johnson 12 Feb '10

12 Feb '10

In our computer lab, there are 6 Centos 5.4 workstations. There is an HP printer with jet direct card. It often works. But sometimes users come and get me saying the printer is broken, but it is actually working fine for *most* of the workstations. On the troubled system, I run system-config-printer and I check the printer in question (under properties) and I see the printer has been disabled. I mean, the box by the word Enabled is empty. After I manually (use lprm) remove the print jobs, and set the printer to Enabled, then the print queue will start working again. I've checked the files in /var/log/cups and there's nothing evident. error_log has nothing. We have had the problem during the year (that others have reported in this list). When trying to print some pdf files from Evince, the symptom of the problem is that the pdf files don't print. They seem to "clog" the printer. When that happens, I have seen the Enabled box come unchecked in the printer configurator. However, the most recent problems are not associated with the use of Evince. I would really appreciate some tips about how to bugshoot this problem. pj ps. The Cups server is running on the system in question, lpq shows lots of print jobs waiting. -- Paul E.

Mount USB disk at startup?
by Mogens Kjaer 11 Feb '10

11 Feb '10

I have a CentOS 5 machine with an external 500G USB disk, formatted with JFS. How do I get this to mount automatically at boot time? If I add to /etc/fstab: /dev/sdb1 /var/video jfs defaults 1 2 fsck.jfs complains at boot time: Error: Cannot open device /dev/sdb1 Usage: fsck.jfs ... ... Give root password for maintenance ... If I log in with the root password, /dev/sdb1 is present, and I can run fsck.jfs -f /dev/sdb1 without problems. After ctrl-D it reboots, and gives the above error again. I have to log in as root, remount,rw / and remove the /dev/sdb1 line from /etc/fstab to get it to boot. The problem is not related to JFS; it occurs with an external ext3 file system as well. How do I mount /dev/sdb1 automatically at boot?

disk I/O problems with LSI Logic RAID controller
by Fernando Gleiser 11 Feb '10

11 Feb '10

we're having a weird disk I/O problem on a 5.4 server connected to an external SAS storage with an LSI logic megaraid sas 1078. The server is used as a samba file server. Every time we try to copy some large file to the storage-based file system, the disk utilization see-saws up to 100% to several seconds of inactivity, to climb up again to 100% and so forth. Here are a snip from the iostat -kx 1: Device: rrqm/s wrqm/s r/s w/s rkB/s wkB/s avgrq-sz avgqu-sz await svctm %util sdb1 0.00 133811.00 0.00 1889.00 0.00 513660.00 543.84 126.24 65.00 0.47 89.40 sdb1 0.00 138.61 0.00 109.90 0.00 29845.54 543.14 2.54 54.32 0.37 4.06 sdb1 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 sdb1 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 sdb1 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 sdb1 0.00 134680.00 0.00 1920.00 0.00 526524.00 548.46 126.06 64.57 0.47 90.00 sdb1 0.00 142.00 0.00 74.00 0.00 20740.00 560.54 1.25 45.14 0.47 3.50 sdb1 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 sdb1 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 sdb1 0.00 0.00 1.00 0.00 4.00 0.00 8.00 0.01 14.00 14.00 1.40 sdb1 0.00 116129.00 1.00 1576.00 4.00 434816.00 551.45 125.47 75.38 0.57 90.30 sdb1 0.00 17301.98 0.00 412.87 0.00 106506.93 515.93 24.59 75.40 0.48 19.80 sdb1 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 sdb1 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 sdb1 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 It happens when I copy a file over the net using samba or when copying/creating a local file It looks like the disk tries to get more than it can handle, then it chokes with data and stales for a few seconds until some buffer empties and it's able to get a bit more data again. It happens in two identical servers, so I'd discard faulty hardware as the cause and look into a miscofiguration issue. Are there any guidelines/docs for heavy I/O tuning? are there any issues with this raid controller? any help will be apreciated Fer
