NAME

       vgextend - add physical volumes to a volume group

SYNOPSIS

       vgextend [-A|--autobackup{y|n}] [-d|--debug] [-h|--help] [-v|--verbose] VolumeGroupName PhysicalVolumePath [PhysicalVolumePath...]

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.

   OPTIONS
       -A, --autobackup y/n
	      Controls automatic backup of VG metadata after the change ( see vgcfgbackup(8) ). Default is yes.

       -d, --debug
	      Enables additional debugging output (if compiled with DEBUG).

       -h, --help
	      Print a usage message on standard output and exit successfully.

       -v, --verbose
	      Gives verbose runtime information about lvextend's activities.

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".

DIAGNOSTICS

       vgextend returns an exit code of 0 for success and > 0 for error:

       1  no volume group name on command line
       2  volume group name not given as first argument
       3  no physical volume(s) on command line
       4  invalid volume group name
       5  error checking existence of volume group
       6  inactive volume group
       7  error reading VGDA
       8  volume group is set to not extendable
       9  maximum physical volume number of volume group exceeded
       10 error reading all physical volumes
       11 error setting up VGDA
       12 error extending VGDA in kernel
       13 error writing VGDA to physical volume(s)

       95 driver/module not in kernel
       96 invalid I/O protocol version
       97 error locking logical volume manager
       98 invalid lvmtab (run vgscan(8))
       99 invalid command line

ENVIRONMENT VARIABLES

       LVM_AUTOBACKUP
	      If this variable is set to "no" then the automatic backup of VG metadata is turned off.

       LVM_VG_MAX_BACKUPS
	      This variable determines the backup history depth of kept VGDA copy files in /etc/lvmconf. It  can  be  set  to  a  positive  number
	      between 0 and 999.  The higher this number is, the more changes you can restore using vgcfgrestore(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".
