vgextend(8)


NAME

   vgextend --- add physical volumes to a volume group

SYNOPSIS

   vgextend   [-A|--autobackup   {y|n}]   [--commandprofile   ProfileName]
   [-d|--debug]     [-h|-?|--help]      [--reportformat      {basic|json}]
   [--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-
   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
