Creating a new VG is my worst-case scenario, but that will be expensive 
in terms of time - time during which I cannot do expansion of volumes.  
It's a little frustrating.

How risky is the idea of editing a backup file and doing the restore?  If 
I screw it up, I can always do a re-restore of the proper data, no?

Thanks...
