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.
- --force
- Necessary to restore metadata with thin
pool volumes.
WARNING: Use with extreme caution. Most changes to thin metadata cannot
be reverted. You may lose data if you restore metadata that does not match
the thin pool kernel metadata precisely.
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.
