High CPU usage for migration kernel process
by Andy Armstrong 29 Mar '06

29 Mar '06

I've got a CentOS 4.3 box here which is exhibiting crazy (I think) CPU load on one of the four migration kernel processes: # ps ax | grep migration 2 ? S 0:08 [migration/0] 4 ? S 112:23 [migration/1] 6 ? S 2:48 [migration/2] 8 ? S 0:11 [migration/3] It's running kernel 2.6.9-34.ELsmp. Does anyone have any idea what might cause that? Thanks :) -- Andy Armstrong, hexten.net

Another server hosed
by centos＠911networks.com 29 Mar '06

29 Mar '06

Hi, Just upgraded a remote 4.1 server [basically Samba] with yum update. Went through the process and every showed OK, when I did a restart, the only thing working is ping. I could ping it, but that's it. Could not connect anymore through SSH, could not connect through SMB. My smb.conf is still there and it still shows my settings. Testparm -L reports the correct info, but nobody can connect. I now have the server being shipped back. Anybody also having problems? -- Thanks http://www.911networks.com When the network has to work

Not able to install Centos 4.2
by Ravi Kumar. 29 Mar '06

29 Mar '06

Hi, Last week I bought a new system & downloaded Centos 4.2. Here is the detailed configuration of the PC: a) Seagate 80GB Sata HDD: Model Number:ST3808110AS b) ASUS ADN-VM Mother board c) AMD 3000+ 64bit d) Other things are common & dont think they are required in this context. I am not able to install Centos 4.2. After the step to check install media, I get this message: "No hard drives have been found. You probably need to manually choose device drivers for the installation to succeed. Would you like to select drivers now?" If I choose yes, I am shown a list of device drivers. I tried some of them, but nothing worked. I have tried installing both 32 bit & 64 bit versions of Centos 4.2. Each of them gave the same message. I googled a bit, but could not get anything to work for me. The HDD is installed properly. I was able to install another flavor of Linux (Mandriva). I did not try with Centos 4.3 because I have heard that Centos 4.2 fully supports SATA disks. Please help, Thanks & regards, Ravi.

ATI Radeon Mobility M6 LY & IBM Thinkpad R40
by Max 28 Mar '06

28 Mar '06

Does anyone have any experience with the combination of a Thinkpad R40 and the ATI Radeon Mobility M6 LY video chip? I've had CentOS 4.1, 4.2, and now 4.3 running just great with 1024x768 resolution, but according the IBM specs, this chip is capable of 1280x1024. A quick lspci -v | grep ATI spewed the following: 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility M6 LY (prog-if 00 [VGA]) I can successfully change the settings under the display menu to 1280x1024, but upon restarting X the default greeter crashes. After that, it picks another greeter and allows me to log in, with it still picking 1024x768. I've played around with trying to manually change the settings in /etc/X11/xorg.conf file. I've tried various depth settings to no avail. The section identifying the card in xorg.conf is: Section "Device" Identifier "Videocard0" Driver "radeon" VendorName "Videocard vendor" BoardName "ATI Radeon Mobility M6" EndSection According to what I've been reading, that's what is supposed to be there. I've found a few things stating that DRI could be a problem, but I'm not too familiar with this. Also, a friend has an R40 but has the ATI Mobility Radeon 7500 chip, instead of the M6 like mine. He's also running CentOS 4.3 and having the exact same problem I'm having. Same deal, according to the IBM specs his chipset as well as mine should be capable of 1280x1024. Any thoughts or related experience with this? If not, it's not a huge deal, I've been using it 1024x768 for well over a year now, but the extra resolution would be wonderful. Thanks! Max

Re: [CentOS] Server hosed... maybe?
by Jay Leafey 28 Mar '06

I THINK I found the problem. As usual, a user/keyboard disconnect error. :^} I rebooted the box this morning into single-user mode and started looking at config files, comparing them to it's twin. Nothing obvious jumped out (of course). I ran authconfig and turned off LDAP authenticaion, tne rebooted the box. Once it came back up, I was able to log in. I re-ran authconfig and turned LDAP authentication back on and was able to log into a VC or remotely via SSH with no problems. I did see another difference that may or man not have had anything to do with it. The "kernel" line in grub.conf had "console=tty0" at the end, but only on the box I was having problems with. It had been uses with a serial console a while back, but not any more. I'm not sure if removing it had anything to do with the problem, but it's working now. I'm going to try to recreate the problem, so I may have something more definitive later. Anyway, it seems happy now. -- Jay Leafey - Memphis, TN jay.leafey(a)mindless.com

Server hosed... maybe?
by Jay Leafey 28 Mar '06

28 Mar '06

I was busy congratulating myself about NOT having a problem with updating my CentOS-4 servers when I ran into a problem with a couple of CentOS-3 servers. The Gods hate the proud... Anyway, I updated two identical servers recently and got the new kernel (2.4.21-40) along with the new initscripts, vixie-cron, squid, and gnupg packages. I waited until the weekend to reboot one of the two boxes and was encouraged to see that it appeared to come up OK and all the servies started with no apparent problems. Later on I tried to log in via SSH and was unable to get in. The login apparently succeeded, but I got no response at all after the password entry. I wasn't able to log in via the console either, same lack of response. I rebooted (ctl-alt-del) into single-user mode, which worked fine, and set up syslog to send all messages to /dev/tty12 for debugging purposes and enabled sysrq, then booted back into runlevel 3. Again, no response after the username/password entry and no messages on tty12 indicating any problems. Just no shell response at all on root or any of the user accounts set up on the system. The box is set up to authenticate against LDAP, but as I mentioned there were no errors from the syslog output that seemed relevant. I'm probably going to set up a shell on one of the virtual consoles to debug this some more, but thought I might ask if anybody else has seen anything like this. All other services (http and a Sun directory server) start up fine, but I cannot get a shell in multi-user mode. I'd like to avoid a rebuild, but that would not be catastrophic as this box is part of a redundant pair. Anybody got any constructive thoughts on this? -- Jay Leafey - Memphis, TN jay.leafey(a)mindless.com
