[linux-lvm] PV#s are not unique



Hi,

I have the following problem:

I tried to pvmove PEs off of a PV and to remove that PV using vgreduce.
Unfortunatly it looks as if it did not really work. Now vgscan does not
find my VG vg_stuff any more.


I assume this might be the reason:

| marvin:~# pvdisplay /dev/ide/host?/bus?/target?/lun0/part1 | grep '^PV#'
| pvdisplay -- no physical volume identifier on "/dev/ide/host0/bus0/target0/lun0/part1"
| 
| PV#                   3
| PV#                   6
| PV#                   6
| PV#                   4
| PV#                   2
| PV#                   1
| PV#                   3

[PV#s are not unique]

All 7 PVs belond to the same volume group (VG Name: vg_stuff). Now when
I run vgscan, it does not detect this volumegroup. pvscan shows the PVs
as associated to an unknown VG.

Any idea on how to recover from this?  I'm using Logical Volume Manager
Tools Version 1.0.1-rc4 and kernel version 2.4.12-xfs-lvm1.0.1rc4.

Thanks in Advance,
					yours,
					peter
