PXE boot, Kickstart NFS install and %include...
by Ron Loftin 01 May '06

01 May '06

Hi Will, I saw your question in the digest version of the list, and thought you might be interested in my solution. I do have it working, and there are a couple of points that I didn't see mentioned in the other parts of this thread, or just were mentioned in passing. The following is a kickstart file for a workstation install on my network. ******************** Begin example ks file *************************** # # Custom partitioning and package selection on mirrored 4.5GB SCSI disks # # nfs --server=server --dir=/export/os-cd/centos/4/os # Use NFS installation media lang en_US.UTF-8 # Language used during installation process langsupport en_US.UTF-8 # Language module(s) to install keyboard us # System keyboard text # Install in text mode %include /mnt/ks/centos/4/ks/general-setup %include /mnt/ks/centos/4/ks/disp/sun-21-inch %include /mnt/ks/centos/4/ks/fw/disabled %include /mnt/ks/centos/4/ks/dsk/4gb-scsi-mirror %include /mnt/ks/centos/4/ks/pkg/ws %include /mnt/ks/centos/4/ks/pkg/cd-burn %pre # # Mount the KickStart tree # mkdir /mnt/ks mount server:/export/install/rhl/kickstart /mnt/ks # # Save DNS config # cp -p /etc/resolv.conf /tmp # %include /mnt/ks/centos/4/ks/post-scripts %include /mnt/ks/centos/4/ks/boot-mirror-scsi ******************** End example ks file ***************************** ******************** Example disk config module ********************** # # Custom partitioning for mirrored 4.5GB SCSI disks # #Clear the Master Boot Record zerombr yes #Clear all partitions from the disk clearpart --initlabel --all part raid.11 --noformat --asprimary --size 2048 --grow --ondisk sda part raid.12 --noformat --asprimary --size 256 --ondisk sda part raid.13 --noformat --asprimary --size 256 --ondisk sda part raid.14 --noformat --asprimary --size 1024 --ondisk sda part raid.21 --noformat --asprimary --size 2048 --grow --ondisk sdb part raid.22 --noformat --asprimary --size 256 --ondisk sdb part raid.23 --noformat --asprimary --size 256 --ondisk sdb part raid.24 --noformat --asprimary --size 1024 --ondisk sdb raid / --fstype ext3 --level 1 --device md0 raid.11 raid.21 raid swap --fstype swap --level 1 --device md1 raid.12 raid.22 raid /var --fstype ext3 --level 1 --device md2 raid.13 raid.23 raid /tmp --fstype ext3 --level 1 --device md3 raid.14 raid.24 ******************** End disk config module ************************** The first 5 lines seem to be required in all kickstart files, or at least I have not been able to do it otherwise. The next lines are modules that describe other KS parameters, display config, firewall config, disk partitions and mirroring, and lists of software groups and/or individual packages to install. One VERY IMPORTANT point to remember is shown in the "%pre" script. This is how to make the modules available to anaconda for processing. Just mount the tree where the modules live somewhere on the target system where you can tell anaconda to go read it. Here, I just create a new directory ( /mnt/ks ) and all %include directives reference that tree. Again, all paths must be specified the way that the CLIENT will evaluate them. After that, it's a snap. You can do almost anything you want as far as including other config files, additional pre/post scripts, whatever. The biggest limit I've found so far is the imagination of the person setting up the process. -- Ron Loftin reloftin(a)twcny.rr.com "God, root, what is difference ?" Piter from UserFriendly

troubleshooting kernel crash?
by Kai Schaetzl 29 Apr '06

29 Apr '06

I'm getting kernel crashes on a new machine since it went into production some weeks ago. How can I troubleshoot this? I suspect a hardware problem, but I know too few about the kernel and kernel debugging on Linux to know how I can nail this down with debugging software. Just for reference of what kind these oopses are I quote the last two. The symptom is that the machine stops responding but is pingable. After a reset all is well until the next crash in ten days or so.

Alert icon for yum
by José Alburquerque 29 Apr '06

29 Apr '06

Hi all. I have a simple question: CentOS relies mostly on "yum" to keep systems up to date, although I understand that like on RHEL, "up2date" is also available. On my system I've run both KDE and GNOME as Graphical Desktops under X (though I presently run GNOME), and I've noticed that there is an applet called "CentOS Network Alert Icon" (from the "System Tools" menu) which when run appears in a "status area" in a panel to show whether the system needs updating or not. This applet shows the up2date sources, but my question is: Is there any way to have some sort of similar applet that does this for yum. I just think that when we add repos we usually add them through yum. Also when we update the system we usually use yum. Hence I think it would be better to use an applet similar to up2date's for yum so that there is no need to edit both yum and up2date files and there is consistency between when the applet signals a need for updating and the actual "yum update" command. Am I making sense? I found a site (http://fedoranews.org/tchung/yum-applet/) with the source for a yum applet. I know I can build this for myself, but I was wondering what others on this list think and whether such an applet should be more widely available to the general CentOS audience. Can I go ahead and build this for my system? TIA for your answers. Sincerely Jose Alburquerque
