NAME
vgextend - add physical volumes to a volume group
SYNOPSIS
vgextend [-A|--autobackup y|n] [-d|--debug] [-h|-?|--help] [-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.
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
pvcreate. 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). pvcreate (8), the
device will be initialized with the same default values used with
pvcreate. If non-default pvcreate values are are desired, pvcreate
should be explicitly called prior to calling vgcreate.
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
--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".
