NAME¶
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-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. 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).
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".
