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

I can't remember whether I tried it on 5.x or not, sorry. bootloader --location=mbr --driveorder=sda part /boot --onpart=sda1 --fstype=ext3 part swap --onpart=sda2 --fstype=swap volgroup vg --useexisting logvol / --useexisting --name=root --vgname=vg --fstype=ext3 Because the volgroup already exists you don't need to define a PV for it. Hope this helps, although it doesn't look much different to your config! Regards, Tom
