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 tran-
       sient 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 comman-
       dline 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".
