Following this thread it kind of looks like you worked around
using LVM commands (i.e. removed a VG w/o using lvremove + vgremove).
If so, not a good idea :(
Well, not to my knowledge I didn't. But my knowledge of LVM is very
tiny. All I remember doing was "vgchange -a n".
What does pvscan list ?
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- ACTIVE PV "/dev/md0" of VG "vg0" [109.77 GB / 109.77 GB free]
pvscan -- total: 1 [109.78 GB] / in use: 1 [109.78 GB] / in no VG: 0 [0]
What does vgck say ?
vgck -- VGDA of "vg0" in lvmtab is consistent
vgck -- VGDA of "vg0" on physical volume is consistent

You have disabled it, it's gone.
Don't panik :->
your LVM will reappear, once you enable it again (vgchange -a y)
still, read some docs.
I have read some docs. I've spent hours combing the Net for the
answers, without success.
I *had* a working system. But, I use the LVM commands so rarely, I can
never repeat what I did (notes or not).
piano:/home/dcorbin# sh -x /etc/init.d/lvm start
+ modprobe lvm
+ modprobe lvm-mod
+ '[' -e /proc/lvm ']'
+ '[' -e /etc/lvmtab ']'
+ '[' -x /sbin/vgscan ']'
+ echo 'Setting up LVM Volume Groups...'
Setting up LVM Volume Groups...
+ /sbin/vgscan --verbose
+ /sbin/vgchange -a y --verbose
piano:/home/dcorbin# mount /data
mount: special device /dev/vg0/data does not exist
The reason you hear "panic" in my typing is the last line. :)

Fundamentally, I'm building a critical data file server. LVM has caused
me enough problems and delays, that I'm about ready to bypass it, saying
it is putting my data at risk. Feel free to convince me otherwise.
Thanks
