NAME¶
vgcfgrestore — restore volume group descriptor area
SYNOPSIS¶
vgcfgrestore [--commandprofile ProfileName]
[-d|--debug] [-f|--file <filename>]
[--force] [-l[l]|--list] [-h|--help]
[-M|--metadatatype 1|2] [-t|--test]
[-v|--verbose] VolumeGroupName
DESCRIPTION¶
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.
OPTIONS¶
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.
REPLACING PHYSICAL VOLUMES¶
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.
