[linux-lvm] PVscan Question.

[Heinz J . Mauelshagen]

Ivan,

the output of pvscan is strange already, because it shows /dev/hdg _and_
/dev/hdg1 as PVs both at the same time which is impossible (same for hdc).

Partition tables seem to be messy on those devices.

What does "fdisk -l /dev/hd[cg]" show?

Regards,
Heinz    -- The LVM Guy --
