NAME

6       vgextend - add physical volumes to a volume group
7

SYNOPSIS

9       vgextend  [-A|--autobackup y|n] [-d|--debug] [-h|-?|--help] [--restore‐
10       missing] [-f|--force]  [-t|--test]  [-v|--verbose]  [  PHYSICAL  DEVICE
11       OPTIONS ] VolumeGroupName PhysicalDevicePath [PhysicalDevicePath...]
12

DESCRIPTION

14       vgextend  allows  you to add one or more initialized physical volumes (
15       see pvcreate(8) ) to an existing volume group to  extend  it  in  size.
16       Moreover, it allows you to re-add a physical volume that has gone miss‐
17       ing previously, due to a transient device failure, without  re-initial‐
18       ising it. Use vgextend --restoremissing to that effect.
19
20       If PhysicalDevicePath was not previously configured for LVM with pvcre‐
21       ate (8), the device will be initialized with the  same  default  values
22       used  with  pvcreate.   If non-default pvcreate values are are desired,
23       they may be given on the commandline with the same options as pvcreate.
24       See  PHYSICAL  DEVICE  OPTIONS  for  available  options.  Note that the
25       restore-related options such as  --restorefile,  --uuid,  and  --physi‐
26       calvolumesize are not available.  If a restore operation is needed, use
27       pvcreate (8) and vgcfgrestore (8).

Examples

56       "vgextend vg00 /dev/sda4 /dev/sdn1" tries to extend the existing volume
57       group "vg00" by the new physical volumes (see pvcreate(8) ) "/dev/sdn1"
58       and /dev/sda4".
