[linux-lvm] F7 will not boot after running backup w/snapshot

[Gerry Reno]

I ran a backup today with a snapshot.  Sometime after the backup 
completed but before I could unmount and lvremove the snapshot the 
system became hung.  No choice but to cold boot.  When the system came 
up it showed a kernel panic on the screen.  Looking back up the screen I 
could see that it could not find a device with UUID blahblah for 
VolGroup00 (which is where the / drive is located) and then VolGroup00 
not found.  So ok, no problem, I just figure that the VolGroup00 is 
inconsistent and I can deal with this in rescue mode.  Wrong.  When I 
boot the F7 rescue from the dvd it says "You don't have any Linux 
partitions..."  What!?  I go into the shell but there is nothing under 
/mnt/sysimage.  So how do I recover from this?  How could a snapshot 
cause all this?
