ouch, you ran pvcreate on a volume which already had data on it? From
all I've read, you had better have a good backup laying around, 'cause
you may not be able to get that data back pvcreate, IIRC, wipes out the
If you have the old UUIDs for the physical volumes, you may be able to
write those back to the device using pvcreate -u <old-uuid> on each such
PV, then try vgscan again.
but, as from the man page:
You can not recreate (reinitialize) a physical volume belonging
to an existing volume group.
so, you may be out of luck. But, good luck anyways ...
