restore volume group descriptor area

vgcfgrestore allows you to restore the metadata of VolumeGroupName from a text backup file produced by vgcfgbackup. You can specify a backup file with --file. If no backup file is specified, the most recent one is used. Use --list for a list of the available backup and archive files of VolumeGroupName.

See lvm(8) for common options.
-l
, --list

List files pertaining to VolumeGroupName List metadata backup and archive files pertaining to VolumeGroupName. May be used with the -f option. Does not restore VolumeGroupName.

-f, --file filename

Name of LVM metadata backup file Specifies a metadata backup or archive file to be used for restoring VolumeGroupName. Often this file has been created with vgcfgbackup.

vgdisplay --partial --verbose will show you the UUIDs and sizes of any PVs that are no longer present. If a PV in the VG is lost and you wish to substitute another of the same size, use pvcreate --restorefile filename --uuid uuid (plus additional arguments as appropriate) to initialise it with the same UUID as the missing PV. Repeat for all other missing PVs in the VG. Then use vgcfgrestore --file filename to restore the volume group’s metadata.
