I'm not sure how to do that when I can't even mount the disk.


Any suggestions on what to do next?

I've noticed that lvm archives a volume group configuration when a change is
made to it (under /etc/lvm/archive.. In plain text too!)  By looking at
these I can tell exactly what commands I ran in order to muck things up...

Fri Sep 21 17:56:48 2007:    'vgextend VolGroup00 /dev/sdb2'
Fri Sep 21 18:25:40 2007:    'vgreduce VolGroup00 /dev/sdb2'
Fri Sep 21 18:25:45 2007:    'vgcreate VolGroup01 /dev/sdb2'
Mon Sep 24 18:37:52 2007:    'vgremove VolGroup01'
Tue Sep 25 13:51:10 2007:    'vgcreate VolGroup01 /dev/sdb2'

I can also tell what pv's and lv's belonged to the corresponding VolGroup in
each archive.


(btw, I've seen archived threads from what looks to be an old linux-lvm
specific mailing list.  Anyone know if this still exists?  I can't find it
anywhere)
