VGCFGRESTORE(8) System Manager's Manual VGCFGRESTORE(8)NAME
vgcfgrestore - restore volume group descriptor area
SYNOPSIS
vgcfgrestore [-d|--debug] [-f|--file filename] [-l[l]|--list] [-h|--help] [-M|--Metadatatype1|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 -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 Vol-
umeGroupName.
-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 vgcfg-
backup.
See lvm for common options.
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.

vgextend - add physical volumes to a volume group
SYNOPSIS
vgextend [-A|--autobackup y|n] [-d|--debug] [-h|-?|--help] [--restoremissing] [-f|--force] [-t|--test] [-v|--verbose] [ PHYSICAL DEVICE
OPTIONS ] VolumeGroupName PhysicalDevicePath [PhysicalDevicePath...]
DESCRIPTION
vgextend allows you to add one or more initialized physical volumes ( see pvcreate(8) ) to an existing volume group to extend it in size.
Moreover, it allows you to re-add a physical volume that has gone missing previously, due to a transient device failure, without re-ini-
tialising it. Use vgextend --restoremissing to that effect.
If PhysicalDevicePath was not previously configured for LVM with pvcreate (8), the device will be initialized with the same default values
used with pvcreate. If non-default pvcreate values are are desired, they may be given on the commandline with the same options as pvcre-
ate. See PHYSICAL DEVICE OPTIONS for available options. Note that the restore-related options such as --restorefile, --uuid, and --physi-
calvolumesize are not available. If a restore operation is needed, use pvcreate (8) and vgcfgrestore (8).
OPTIONS
See lvm for common options.
PHYSICAL DEVICE OPTIONS
The following options are available for initializing physical devices in the volume group. These options are further described in the
pvcreate man page.
-f, --force
-y, --yes
-Z, --zero y|n
--labelsector sector
--metadatasize size
[--metadataignorey|n]
--pvmetadatacopies copies
--dataalignment alignment
--dataalignmentoffset alignment_offset
Examples
"vgextend vg00 /dev/sda4 /dev/sdn1" tries to extend the existing volume group "vg00" by the new physical volumes (see pvcreate(8) )
"/dev/sdn1" and /dev/sda4".
