You can get the UUIDs from the HDDs with blkid. Just type at the CLI. Get the
number for the correct partition and stick it in the fstab and
grub.conf if needed.
You can always use the OS DVD to go into rescue mode (F5) to fix things.

See the e2label man page
     # e2label /dev/sdaX   --shows current fileystem label
     # e2label /dev/sdaX newLabel -- assigns a new label to the filesystem

Hmm... where does e2label stores the filesystem label? I don't know.
I'd guess that dd would copy them, but not rsync. Anyone care to comment?

just be cautious and do a bit of your own reading before committing changes.
