I'd like to automate the upgrade from CentOS 4.6 to 5.1 as much as possible. Since upgrades per se are not really recommended, I'm planning to do a kickstart installation. However, I want to leave one of the existing partitions (/scratch) untouched during the installation. Here is my current layout (LogVol00 is swap so not shown in the df output below):
# df -hl Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup00-LogVol01 36G 11G 24G 30% / /dev/sda1 99M 17M 78M 18% /boot /dev/mapper/VolGroup00-LogVol02 36G 9.7G 24G 29% /scratch # vgscan Reading all physical volumes. This may take a while... Found volume group "VolGroup00" using metadata type lvm2 # pvscan PV /dev/sda2 VG VolGroup00 lvm2 [74.41 GB / 32.00 MB free] Total: 1 [74.41 GB] / in use: 1 [74.41 GB] / in no VG: 0 [0 ] # lvscan ACTIVE '/dev/VolGroup00/LogVol01' [35.75 GB] inherit ACTIVE '/dev/VolGroup00/LogVol02' [35.72 GB] inherit ACTIVE '/dev/VolGroup00/LogVol00' [2.91 GB] inherit
I've tried various alternatives of specifying the disk layout in the kickstart file, and here is my latest attempt:
part /boot --fstype ext3 --onpart sda1 part pv.2 --noformat --onpart sda2 volgroup VolGroup00 --noformat --useexisting --pesize=32768 logvol swap --useexisting --fstype swap --name=LogVol00 -- vgname=VolGroup00 logvol / --useexisting --fstype ext3 --name=LogVol01 -- vgname=VolGroup00
But when I try to install CentOS 5.1 via kickstart, anaconda complains that "You have not defined a root partition (/), which is required for installation of CentOS to continue". Has anyone successfully installed CentOS 5.X via kickstart and preserved at least one partition on a logical volume, and if so, could you please share your kickstart file?
Thanks, Alfred
