vgextend

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

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-ini-
       tialising 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 pvcre-
       ate.  See PHYSICAL DEVICE OPTIONS for available options.  Note that the restore-related options such as --restorefile, --uuid, and --physi-
       calvolumesize 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".
