NAME

       vgextend - add physical volumes to a volume group

SYNOPSIS

       vgextend  [-A|--autobackup y|n] [-d|--debug] [-h|-?|--help] [-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.

       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
       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).  pvcreate (8), the
       device will be initialized with  the  same  default  values  used  with
       pvcreate.   If  non-default  pvcreate  values are are desired, pvcreate
       should be explicitly called prior to calling vgcreate.

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

       --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".
