vgextend allows you to add one or more initialized physical volumes ( see
) 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).
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.
-Z, --zero y|n
"vgextend vg00 /dev/sda4 /dev/sdn1" tries to extend the existing volume
group "vg00" by the new physical volumes (see
) "/dev/sdn1" and /dev/sda4".
