I got a new disk, and created LVMs on it. I copied the filesystems OK.
But, how do I get the new disk mounted as /? For that matter, what
determines what LVM gets mounted where? I'm guessing it's part of the LVM
information. I noticed that system-config-lvm has options to select where
logical partitions get mounted.
I hope I don't need to switch it by editing with system-config-lvm - because
if I mess that up, I'm basically screwed.
I tried editing grub.conf:
title Fedora Core (2.6.15-1.1948_FC5)
root (hd0,2)
kernel /vmlinuz-2.6.15-1.1948_FC5 ro root=/dev/VolGroup00/LogVol00
rhgb quiet
initrd /initrd-2.6.15-1.1948_FC5.img
title Fedora Core (2.6.15-1.1948_FC5)#2
root (hd0,2)
kernel /vmlinuz-2.6.15-1.1948_FC5 ro root=/dev/7200rpm/LogVol02 rhgb
quiet
initrd /initrd-2.6.15-1.1948_FC5.img
But if I select #2 it panics saying it can't find /dev/root, (or something
like that).
Here's some info:

Reading all physical volumes. This may take a while...
