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
