[linux-lvm] vgcfgrestore error !

[Heinz J . Mauelshagen]

Igor,

you need to figure out, which Physical Volumes (PVs) belong to your VG lvm1
by running 'vgcfgrestore -ll -n lvm1'. Please check for the PV list at
the end of the output.

Then restore the LVM metadata by running 'vgcfgrestore -n lvm1 /dev/hdWhatever`
on every of those.
Afterwards run 'vgscan;vgchange -ay lvm1', which should revive lvm1.

What error happend in the first place causing lvm1 to disapear?
Do you use recent LVM software?

Regards,
Heinz    -- The LVM Guy --

    Nevertheless it needs not so stupid people to solve them ***
