When did you re-install GRUB (grub-insall)? And when you did, did you have it use the _new_ grub.conf?
The system booted, but got only as far as 'Red Hat nash' ... then complained that it couldn't find vg0. (the volume group on the other disk). I can't get into single-user
mode
when booting this single drive. I'm trying to do this whole thing non-destructively so that the original drive is a backup, until we confirm that the
new
drive is behaving well.
Consider booting the CentOS CD #1 in "rescue" mode. Let it find your root and then chroot and run grub-install.
Are these steps correct (and they should be without LVM) or is there something much easier and obvious that I'm
missing?
I could, I suppose, add the new parition into the original volume group, and do the 'pvmove' dance to get things over
(as
explained briefly in the LVM-HOWTO on Red Hat's site) but
it
wouldn't leave a bootable system on the original drive.
It's best to treat the two sets of discs/volumes as different, and never put them in the same system. Again, use CD #1 to boot into "rescue" mode, chroot and run grub-install with only the new discs/volumes connected.
