the filesystem can't be mounted (which is the really worrying part) so i can't 
fsck it.

root at connect4:~# mount -t ext3 /dev/vg1/lv1 /data
mount: /dev/vg1/lv1 is not a valid block device
root at connect4:~# ls /dev/vg1/
total 124
dr-xr-xr-x    2 root     root         4096 Feb  6 18:46 ./
drwxr-xr-x   22 root     root       118784 Feb  8 14:19 ../
crw-r-----    1 root     disk     109,   0 Feb  6 18:46 group
brw-rw----    1 root     disk      58,   0 Feb  6 18:46 lv1

the fsck that i mentioned previously was run on the other (available) 
filesystems, thinking that perhaps the LVM binaries (or some other related tool)

had been corrupted.
