But, ls -ltar /dev/vg0 is essentially the same.

David,

try vgscan then which should bring your device node back.

This all looks ok.

Doesn't "vgchange -a y" bring your VG back ?
If not so, try "vgscan ; vgchange -ay".




piano:/home/dcorbin# vgchange -ay
vgchange -- volume group "vg0" already active

So, it appears that the VG IS there.
----
piano:/home/dcorbin# mount -t reiserfs /dev/vg0/data /data
mount: special device /dev/vg0/data does not exist

/dev/vg0/data is the device I used to use to mount it, and the error message is correct if I look at my filesystem (it doesn't exist).
----
piano:/home/dcorbin# mount -t reiserfs /dev/vg0/group /data
mount: /dev/vg0/group is not a block device


I tried this command because /dev/vg0/group is the only device in /dev/vg0
----
Here are some other commands that I tried that may or may not tell you something...


piano:/home/dcorbin# lvscan lvscan -- no logical volumes found
piano:/home/dcorbin# ls -ltar /dev/vg0
total 28
