VGEXTEND(8)VGEXTEND(8)NAMEvgextend - add physical volumes to a volume group
SYNOPSISvgextend [-A|--autobackup y|n] [-d|--debug] [-h|-?|--help] [--restore‐
missing] [-f|--force] [-t|--test] [-v|--verbose] [ PHYSICAL DEVICE
OPTIONS ] VolumeGroupName PhysicalDevicePath [PhysicalDevicePath...]
DESCRIPTIONvgextend 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 miss‐
ing previously, due to a transient device failure, without re-initial‐
ising it. Use vgextend--restoremissing to that effect.
If PhysicalDevicePath was not previously configured for LVM with pvcre‐
ate (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 pvcreate.
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 pvcre‐
ate 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".
