Can you recall how this tokk place?

I ask to get an idea if LVM has to be enahnced or fixed.

If you want to restore your volume group description to the disks:
------------------------------------------------------------------

   Please start by doing a backup of /etc/lvmconf/* because there are up
   to 10 backups in a history of your volume group configuration.

   for p in /dev/YourInvolvedDiskSpecials; do
      vgcfgrestore -n YourVolumeGroup -f PathToYourVolumeGroupBackup $p
   done


   PathToYourVolumeGroupBackup could be /etc/lvmconf/VourVolumeGroupName.conf

   - or -

   /etc/lvmconf/VourVolumeGroupName.[1-9].conf


   BTW: with "vgcfgrestore -n YourVolumeGroup -ll -f PathToYourVolumeGroupBackup
        you can look into the backup file and decide, if this is the one
        you want to be restored.


If you just want to initialize all involved and now useless PVs:
----------------------------------------------------------------

   pvcreate -ff /dev/YourPVX ... # insert all involved disk/partition specials


Regards,
Heinz
