I wonder if this is why I lost all of my data last Thursday...

vg w/ 2 pv's (hde1 & hdg1) and 3 lv's.  Add a pv (hdc1) and
reboot, and all of a sudden, even though the vg is still there,
with 3 pv's and 3 lv's, the lv's won't even fsck (bad magic
number in superblock -- doesn't even look like a filesystem was
even there).  I though maybe it had a problem w/ rearranging the
pv's or something...  How else could it completely lose track
of my data?

It was kernel 2.4.0 w/ the several-line vg_extend patch, and the 0.9
tools...

Oh, well -- just a WAG...
