Well, that appears to have solved the immediate probelm.  Now, help me 
get through the next one....

Attempts to access the logical volume I used to fail. 

piano:/etc# ls -ltar /dev/vg0
total 28
crw-r-----    1 root     disk     109,   0 Feb 23 13:35 group
drwxr-xr-x   10 root     root        24576 Feb 23 13:35 ..
dr-xr-xr-x    2 root     root         4096 Feb 23 13:35 .
piano:/etc# ls -ltar /dev/vg0/group
crw-r-----    1 root     disk     109,   0 Feb 23 13:35 /dev/vg0/group
piano:/etc#

I'm concerted that "group" is /dev/vg0, instead of "data".

Ideas on how I can recover this?
