fsck file system is mounted
by centos＠911networks.com 17 May '09

17 May '09

Hi, Is there a way to run fsck or any other program to check if there is drive problem. I don't want it repaired, now, but maybe later on. I can't shutdown the system and reboot in single user-mode. All suggestions are welcomed. -- Thanks http://www.911networks.com When the network has to work

[OT] Anyone use a Blackberry?
by Jason Todd Slack-Moehrle 17 May '09

17 May '09

Hi All, I know off topic, but I just cant get solutions and you all are always so helpful. I have a blackberry curve 8310 and I really need to keep track of clients, their e-mails, notes, pdfs, etc. basically everything about a customer. I want to deploy it here in my apartment (I have a static IP) and either have my BB connect or sync at the end of the day or something. I just cannot find a low cost (or free) solution where I can make this happen. Does anybody know of anything? I run OS X (primarily), Windows (for on the go on a netbook) and CentOS. -Jason

yum-updatesd no longer working
by Stewart Williams 16 May '09

16 May '09

I recently enabled yum-updatesd on two identical servers and configured it to notify me of updates via e-mail. This worked fine to start with and it notified me on both machines when the kernel-2.6.18-128.1.10.el5.x86_64.rpm update was released last week. However, today I realised that yum-updatesd was not running and thought it was due to rebooting after the kernel update and that I'd forgotten to set it to start at boot. But this was not the case, it is set to start, however running '/sbin/service yum-updatesd start' yields: yum-updatesd dead but subsys locked I have tried removing /var/lock/subsys/yum-updatesd, but when I restart the service it says [OK] and yum-updatesd doesn't run, but the lock file is re-created. yum-updatesd --debug does not help either. Any help or idea's greatly appreciated. Thanks

Yum update gone bad...
by Anthony Kamau 16 May '09

16 May '09

Morning list! I have a situation that was brought about by a system crash during a yum update. The motherboard suffered a catastrophic failure due to busted CAPS. Lucky for me (or so I thought at the time), I had a spare, identical motherboard as the one that failed. I replaced the dud board and rebooted. This machine runs headless and is my primary (personal/home) mail server. I normally access the booting console via hyper terminal when I need to change boot parameters or just watch the system boot up! Getting to the point, nothing comes up at all on the terminal screen. So I hooked up a monitor and keyboard (even a mouse) to check what was going on. What I noticed immediately was that the kernel screen selection screen did not appear! Instead, I just got a message at the bottom on the screen stating "Grub Loading Stage 2" or something to that effect. Straight from there, was the usual scrolling text up to the point where SELinux starts. Then nothing displays at all until the final login screen. Not even the "Nash" screen that prompts one to enter "I" for interactive start-up appeared! Could someone enlighten me on what I could check? I have reinstalling all packages that were installed just before and after the system crash to no avail. This is a system that was running CentOS 5.3 final and I was updating several packages including upgrading the kernel from 2.6.18-128.1.6.el5 to 2.6.18-128.1.10.el5. Cheers, tkb.

can non-owner change file group setup?
by mcclnx mcc 16 May '09

16 May '09

We are tried to count how many files belong to certain group. Our system administrator told us "non-owner" can easy change file group name to another. I have been tried several combination and never successful (only ROOT can change file group to other name). Does anyone know how "no-owner" can change file group name? Thanks. ______________________________________________________________________________________________________ 付費才容量無上限？Yahoo!奇摩電子信箱2.0免費給你，信件永遠不必刪！ http://tw.mg0.mail.yahoo.com/dc/landing

Preventing hour-long fsck on ext3-filesystem
by Bernhard Gschaider 16 May '09

16 May '09

Hi! I'm justing in the process of setting up a new fileserver for our company. I'm installing CentOS 5.3 (64 bit) on it. One of the "problems" with it is that it has a 3.5TB filesystem for the user data which I formatted during setup as an ext3. Now my experience with our current fileserver is that a 0.5TB ext3 filesystem needs approx half an hour to complete (and kicks in every so and so reboots or every 180days). My estimate is that for the larger filesystem (and the faster machine) the fsck would need well over an hour (being optimistic). I dread the day when I have to reboot the server and wait for 2hours or more just because the system thought it would be a prudent thing to check the filesystem. My question: - is there another stable filesystem (XFS, ReiserFS ...) in the centosplus-kernel where this could be avoided (fsck is faster) and that is as safe as ext3 - Or would it be better to switch off automatic checking with tune2fs Any opinion/experience welcome. I looked around a bit but couldn't find a good answer Bernhard PS: Sorry for the stupid question, but I'm only part-time admin and testing this myself would take weeks, I guess -- --------------------------------------------------------------------------- DI Bernhard F.W.

Subversion causing Apache to hog memory
by Neil Aggarwal 16 May '09

16 May '09

Hello: I posted this to the subversion list yesterday and have not received a reponse. I am hoping someone on this list will be able to help me. I have a CentOS 5 server running subversion 1.5.6-0.2.el5.rf installed using yum from the rpmforge repository. I am using svnsync to mirror from another repository to the local machine. It is called from a cron job every 5 minutes. After a few days of running fine, I started getting this error from cron: svnsync: DAV request failed; it's possible that the repository's pre-revprop-change hook either failed or is non-existent svnsync: At least one property change failed; repository is unchanged svnsync: Error setting property 'sync-lock': Failed to start '/usr/local/svn/MyProject/hooks/pre-revprop-change' hook Looking in /var/log/httpd/error_log, I see this: Could not execute PROPPATCH. [500, #206] Failed to start '/usr/local/svn/MyProject/hooks/pre-revprop-change' hook [500, #165001] Can't start process '/usr/local/svn/MyProject/hooks/pre-revprop-change': Cannot allocate memory [500, #12] Looking at top, the machine has allocated all of the RAM available. When I stop httpd, the RAM comes back. I rebooted the machine and ran top in a shell. I then issued the svnsync command in another shell. I can see the memory usage going up each time I run the svnsync command but it does not seem to come down even after leaving the machine idle for a while. If I then stop httpd, the memory comes back. It looks like svnsync is somehow causing apache to hog memory. Any ideas? Thanks, Neil -- Neil Aggarwal, (832)245-7314, www.JAMMConsulting.com Eliminate junk email and reclaim your inbox.
