 Although I am using lilo, I suppose it is the same problem I
 Don't know GRUB, but I suppose there is a line which specify your root
 filesystem. You should have something like: /dev/myvg/mylv instead of
 /dev/sdaX or /dev/hdaX or any disk name.

If you already use this naming scheme, I suggest you post you GRUB
configuration file, in order to help us understand how things are
