VGEXTEND(8)                          System Manager's Manual                          VGEXTEND(8)



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
