NAME
vgextend — add physical volumes to a volume group
SYNOPSIS
vgextend [-A|--autobackup {y|n}] [--commandprofile ProfileName] [-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 physi‐
cal volume that has gone missing previously, due to a transient device failure, without
re-initialising 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(8). If non-default
pvcreate(8) values are desired, they may be given on the commandline with the same options
as pvcreate(8). See PHYSICAL DEVICE OPTIONS for available options. Note that the
restore-related options such as --restorefile, --uuid and --physicalvolumesize are not
available. If a restore operation is needed, use pvcreate(8) and vgcfgrestore(8).
OPTIONS
See lvm(8) 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(8) man page.
-f, --force
-y, --yes
-Z, --zero {y|n}
--labelsector sector
--metadatasize size
--metadataignore {y|n}
--pvmetadatacopies copies
--dataalignment alignment
--dataalignmentoffset alignment_offset
Examples
Extends the existing volume group "vg00" by the new physical volumes (see pvcreate(8))
"/dev/sda4" and "/dev/sdn1".
vgextend vg00 /dev/sda4 /dev/sdn1
