[Fwd: [linux-lvm] LVM export]

[Harald Kerndler]

We have found the command vgcfgrestore and we have him tested.
We have follow command used: vgcfgrestore -n vol0 /dev/hda4 and then comes this
error:
vgcfgrestore -- ERROR "pv_read(): PV exported" reading physical volume "/dev/hda4"

Is the VG demaged ?
