Hi,
My initial plan was to do it the way you suggest but it seems that doing
an online resize of the root partition doesn't agree with fsck when it
reboots, the majority of test hosts forced us in to single user mode to
run fsck by hand.
In theory that would work out perfectly if we were building the machines
ourselves as we could run the script and the rebuild without rebooting
into the OS, but we are planning to allow our users to rebuild at a time
that suits them using a grub rebuild option. Thats how we came up with
the idea of resizing during kickstart.

Why not resize your LVM before kickstarting? Seems to me it would be a
lot easier to run a resize script on all the machines while they are up
and running, THEN Kickstart them with the properly sized LVM's.

Subject: Using kickstart to resize existing LVM partitions during a
rebuild
Hi,
We have around 300 RHEL4 boxes that we are looking to upgrade to
Scientific Linux 5, as part of the rebuild we would like to double the
size of our current root partition to allow for future expansion and
because they are getting a bit short on free space.
Our current LVM set up looks like;
/dev/mapper/ifp-slash 15Gb
/dev/mapper/ifp-var 2Gb
/dev/mapper/ifp-log 2Gb
/dev/mapper/ifp-scratch fills the rest of the disk.
We intend to script the shrinking of the ifp-scratch LV before starting
the rebuild to free up 15Gb free space within the volume group which we
would then like to add to the ifp-scratch LV during the rebuild.
During the rebuild the ifp-scratch LV must stay intact as our users dump
a lot of there data there.
The problem that I've been having is that I can't figure out the syntax
required for the logvol line in the kickstart file that will resize the
ifp-slash to 30Gb. Every attempt that I've made so far seems to resize
it to 15Gb as it was before.
If you need any more information please let me know, and thanks in
advance for any help that is offered.
Barry
