 Although I am using lilo, I suppose it is the same problem I
 encountered.
 
 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
configured.

Here is my grub.conf. I regret that my experience with linux, indeed
any form of unix, is somewhat limited.  For obvious reasons the lvm
boot load is not the default.  I have made alterations to rc.sysinit to
properly call lvm-mod when the kernel loads and to the shutdown
script to run vgchange -an.  RedHat's provided rc.sysint has a
dependency on /proc/lvm which cannot be satisfied until after lvm-
mod loads, a rather curious chicken and egg problem.
