But I found a problem with python when I wanted to add a DomU to the xen managed domains. It seems the xmlproc library is missing. I tried to install python-xml (as is recommended for Debian) but there is none for CentOS. libxml2-python is already installed and the only other module with xml in the name is python-lxml which doesn't look like the one I need.

Doing a CP operation would sometimes result in severe lack of responsiveness from that point on. Might take a half hour until I could even kill things and start anew.

Not suggesting that you switch to qmail, with it's recompile the whole [EMAIL PROTECTED] thing every time you change a config option mentality, but it's useful information nonetheless, especially when you get into having multiple mail receipt hosts. The additional complexity of NFS is what seems to have caused this gentleman's problem - not only did sendmail itself have to work properly, so did NFS, DNS, and the spam filter. How to avoid it? Either: 1) Reduce complexity.

Seems to build OK for me (2.6.18-53.1.14.el5-i386) ...
Did it build OK for previous 5.1 kernels?
Do you know where it is picking include/linux/utsname.h from? - it
should be:
/lib/modules/2.6.18-53.1.14.el5/build/include/linux/utsname.h
(which is really under /usr/src/kernels/2.6.18-53.1.14.el5-x86_64)
Where does the output of configure say about this?
James Pearson
Jim,
Yes it is getting it from
/lib/modules/2.6.18-53.1.14.el5/build/include/linux/utsname.h
I had to change the driver configure script :
Original:
if test $kversion.$kpatchlevel = 2.6 -a $ksublevel -ge 19; then
CONFIG_HAVE_INIT_UTSNAME=1
My version:
if test $kversion.$kpatchlevel = 2.6 -a $ksublevel -ge 18; then
CONFIG_HAVE_INIT_UTSNAME=1

[CentOS] corrupted disk/drive issue...
ok... my bad. there is an additional step that has to be done tha t i left out. my apologies. once you've found that you do have the lvms with the: lvm pvscan lvm vgscan lvm lvscan cmds... the lvm(s) might be in an inactive state. if you do a ls /dev and you see that you have /dev/VolGroup00 or something to that effect depending on how you named your lvms... you're ok. if not, then you simply need to activate the lvms by doing: lvm vgchange -ay this will go ahaead and set the lvm(s) to an active state, where it will then show up under the /dev dir... the rest of the steps i provided should work ok.. thanks.. Hi... Ran into an interesting issue during the past week, and figured I'd post the issue, and solution here in case it might come in handy for someone else... The laptop was running, but it was left on with the lid closed for a day or so.. when powered up, the laptop went into a state saying it couldn't find the mounts... hmm.. shouldn't have thought this could happen. figured the drive might screwing up, so i reinstalled FC8. after a few hours, got everything back.. went and plugged the laptop into a power strip that had a short..!! ouch, saw the same behavior.. got sort of nervous, but thought it should be ok (hopefully!) so after another reinstall, got to really wondering what was really going on... didn't think about it.. the laptop was working.. things were cool.. for a day! and after closing the lid, and then reopening.. after another day or so. saw the same behavior. here's what i was seeing: Filesystemtype is ext2fs, partition type 0x83 VolGroup00 using etadata type lvm2 2 logical volumes in volume group VolGroup00 now active VFS: Can't find ext3 filesystem on dev dm-3 mount: error mounting /dev/root on /sysroot as ext3: Invalid argument setuproot: moving /dev failed: No such file or directory setuproot: error mounting /proc: No such file or directory setuproot: error mounting /sys: No such file or directory switchroot: mount failed: No such file or directory at this point, talked to a few people, and started thinking that somehow the disk was getting, had gotten corrupted. so... started to try to see what the drive had, if anything! poped in the FC8 rescuedCD, and went to work.. ran the cmds: lvm pvscan lvm vgscan lvm lvscan since i had installed using the defaults for FC8 LVM, the drive showed that it was basically ok. went ahead and ran fdisk /dev/sda and saw that i indeed had my two partitions /dev/sda1, /dev/sda2 so at this point.. i did a mkdir /dev/sysimage, followed by a mount /dev/VolGroup00/LogVol00 /mnt/sysimage this worked, and got me to a point where i could hopefully fix/repair whatever errs might be on the drive... i then ran e2fsck -y /dev/VolGroup00/LogVol00 after a little hope.. and an amount of time as the system did it's thing, it came back saying how many sectors where corrected, etc... i then rebooted, and the laptop was back up/running as it should! feel free to add to this if you have useful information, or additional insight that you want to share. peace. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] atrpms nvidia cannot load
Hi guys - brand new 5.1 install here and quite happy - but... The nv driver did not work at all for me, fritzy stripes and dots. This is a GeForce 7300 LE which was working happily dual-head under FC6 with the livna nvidia RPMs So I looked around and it seemed like the ATRpms repo via yum was the best option for CentOS. This is what I installed, it worked great with the xorg.conf from the old system. But then I did a 'yum update' to the system and got a new kernel from centosplus (?). Now the nvidia module won't load. It's not happy with the new kernel. I am at a loss as to how to make it happy? what is the best way to install the closed-source drivers? direct from nvidia? recomplile them? Is there some gap between updates kernel and the atrpms modules? and in advance I am SORRY if this has been beat to death. I know ~75% of the traffic on the Fedora list was about nvidia woes and flames. Lame, but the DRI does work well on these and my daughter likes to play games. best, Sam ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Rudi Ahlers wrote on Mon, 31 Mar 2008 16:38:12 +0200: But, can one install a specific version of a package from the yum command? Sure. You do a find and then get all available packages. Then you pick the one you want. You need to use it's long name then, of course. There might be a new problem then, though: more dependencies on older versions of packages. So, depending on the whole scenario it might be easier to use rpm instead of yum.

Hopefully, someone will chime in to point out any flaws here. Current System/OS on single 10GB IDE disk /dev/hda2 = swap @ 1GB /dev/hda1 = / @ 9GB Current system/OS is not in an LVM volume. 1.

Reboot to normal startup on the new mirrored / swap. Step 21 needs to boot cleanly. Step 22 will remove your last chance to revert to the old setup by installing the original boot disk as hda. If something goes bad here, may need to restore from backup. 22. Add in 2nd disk to md10 mirror set: mdadm --grow /dev/md10 --raid-devices=2 mdadm --add /dev/md10 /dev/hdb1 23.

System will be at normal state when mirror sync is finished One thing to add. Don't put the second drive as a slave to the first. Most times when a PATA drive goes down it will lock the entire channel until a reboot. The whole point of having the mirrors is to keep running on a drive fail.

Hi Sam, I would recommend the nvidia driver on RPMForge as it's a dkms-based driver, meaning that it gets automatically rebuilt upon a kernel upgrade. You'd need to enable the RPMForge repo, see here: http://wiki.centos.org/Repositories and then install dkms and the nvidia driver for your card yum install dkms nvidia-x11-drv Check that the dkms_autoinstaller service is set to run at the appropriate run levels and you should be good to go (you may need to first uninstall the existing ATRpms driver package). Oh - you'll probably also need the devel stuff present on your system such as kernel-headers, kernel-devel and gcc etc for the driver to compile. Hope that helps. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

If you're asking because you're concerned about backup/restore then you'll want to forget about the location of the data files and instead use the mysqldump command to make your backups. If you're interested from the capacity planning standpoint then the answer is that CentOS configures MySQL to live in the /var/lib/mysql directory.

[CentOS] Icon .png file loading error after graphics driver upgrade
Dear, I updated my nvidia graphics driver on one of the CentOS boxes. When I log in my account, icons are not displayed correctly. They are displayed as small empty squares, and there are error messages like Fater error: failed to load file name.png : version error for each icon. If I log in as super user, everything is OK. Icons are OK. No error messages. Do you have any idea? Thank you. -john ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] RAID1 migration - /dev/md1 is not there
I am trying to convert an existing IDE one-disk system to RAID1 using the general strategy found here: http://lists.centos.org/pipermail/centos/2005-March/003813.html But I am stuck on one thing - when I went to create the second md device with mdadm, # mdadm --create /dev/md1 --level=1 --raid-devices=2 /dev/hdb2 missing mdadm: error opening /dev/md1: No such file or directory And indeed, ls /dev/md* shows only md0, which worked fine.

[CentOS] raid1 custom initrd and yum
OK sorry to hammer the list but one more question - having almost got the drives mirrored and happy - since I have created a custom initrd that has the raid1 drivers in it, do I now have to tell yum to ignore kernel updates? Will the stock kernel render me unbootable? Actually I am not 100% sure the initrd I created # mkinitrd -f --preload=raid1 /mnt/tmp/initrd-`uname -r`.img `uname -r` is even being used, because lsmod still lists a raid1 module. Wouldn't it be embedded in the running kernel and thus not in the module list? either way I am a little confused and this is important ;) best regards and thanks to all for the help, Sam ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] How to find available groups for installation via yum ?
Hi All, Short description of the problem: - I would like to install the complete 'xfce' desktop on CentOS5.x I've tried: yum groupinstall xfce yum groupinstall xfce4 yum groupinstall xfce* yum groupinstall xfce4* yum groupinstall xfce4.2 yum groupinstall xfce4.1 yum groupinstall xfce4.3 yum groupinstall xfce4.4 yum groupinstall xfce4.4.2 etc etc ... nothing worked then I've started googling the net and finally I found the magic combination. One very merciful soul posted the golden combination. yum groupinstall XFCE-4.4 This did the trick. God bless him/her and all his relatives. He/She deserved it. question: Is there a way to check which packages are available for the installation as a 'group' using yum ?
