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).
OPTIONS
See lvm for common options.

volume group. These options are further described in the pvcreate man page.

) "/dev/sdn1" and /dev/sda4".
