[linux-lvm] vgchange -a y /dev/System fails

[Heinz J . Mauelshagen]

Marc,

I am afraid you need to figure out the last metadata backup in /etc/lvmconf/
which *doesn't* contain the flaky snapshot(s).

You didn't mention the name of you VG so let's say it was 'A'.

You can do that with "vgcfgrestore -f /etc/lvmconf/A.conf.1.old -n A -ll".
Replace the '1' in the metadata backup filename above with 2, 3 and so on
(you should have a default of up to 9).
After you found one (say #3), remember all you PVs belonging to that VG and run

pvcreate -yff /dev/AllYourPVsBelongingToA
for pv in /dev/AllYourPVsBelongingToA
do
   vgcfgrestore -f /etc/lvmconf/A.conf.3.old -n A $pv
done
vgscan
vgchange -ay A

That should be it (crossing fingers ;-)
