PVSCAN reveals:
[root@astro melinda]# /sbin/pvscan VG data differs between PVs /dev/sdd2 and /dev/sde2 1 PV(s) found for VG vg01: expected 0 Out of memory. Requested 4006555252 bytes. Couldn't allocate logical volume maps. PV /dev/sdd1 is in exported VG vg02 [9.85 GB / 0 free] PV /dev/sde1 is in exported VG vg02 [19.54 GB / 0 free] Total: 2 [0 ] / in use: 2 [0 ] / in no VG: 0 [0 ]
/dev/sdd2 and /dev/sde2 have both been reformatted as ext3 fs and their partition type was changed to linux fs using fdisk.
The memory error I haven't seen before (we have 3GB) but I installed a new kernel the other week maybe that is the cause /var/log/messages said:
Sep 8 16:17:15 astro kernel: ide-scsi: hda: unsupported command in request queue (0)

I don't want to do
dd if=/dev/zero of=/dev/sdd2 bs=512
as /dev/sdd2 now has data on it.
If I look at both drives in fdisk only the parition /dev/sdd1 and /dev/sde1 which make up VG02 are set to "Linux LVM".
Is there someway to rename VG02 as VG01 maybe? I am at a loss.
Many Thanks,

Melinda,
Does pvscan show /dev/sdd2 as a Physical Volume ?
If so, there's still LVM metadata on /dev/sdd2 in the first sector. In case the partition is unused (no filesystem etc.), a
dd if=/dev/zero of=/dev/sdd2 bs=512
should remove the PV.

Hello,
After my couple of disks died I have been left with one working volume group vg02 and
one non-existant volume group vg01 which I would like to remove.
Since /dev/sdd2 and /dev/sde2 no longer exist I am unable to remove the volume group with the usual method:
/sbin/vgremove vg01 VG data differs between PVs /dev/sdd2 and /dev/sde2 Volume group "vg01" doesn't exist
Actually /dev/sdd2 does still exist as a normal formatted linux partition so I don't want to damage that while trying to remove my volume group.
How do I tell lvm that vg01 no longer exists? It is not in lvmtab so I am unsure where it store this info.
Many Thanks,
melinda
