vgextend \(em add physical volumes to a volume group

.I VolumeGroupName PhysicalDevicePath
.RI [ PhysicalDevicePath ...]
.SH DESCRIPTION
vgextend allows you to add one or more initialized physical volumes
(see \fBpvcreate\fP(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
\fBvgextend \-\-restoremissing\fP to that effect.
.sp
If \fIPhysicalDevicePath\fP was not previously configured for LVM with
\fBpvcreate\fP(8), the device will be initialized with the same
default values used with \fBpvcreate\fP(8). If non-default
\fPpvcreate\fP(8) values are desired, they may be given on the
commandline with the same options as \fPpvcreate\fP(8). See
.B PHYSICAL DEVICE OPTIONS
for available options. Note that the restore-related options such as
.BR \-\-restorefile ", " \-\-uuid " and " \-\-physicalvolumesize
are not available. If a restore operation
is needed, use \fBpvcreate\fP(8) and \fBvgcfgrestore\fP(8).
.SH OPTIONS
See \fBlvm\fP(8) for common options.
.SH PHYSICAL DEVICE OPTIONS
The following options are available for initializing physical devices in the
volume group. These options are further described in the
\fBpvcreate\fP(8) man page.

(see \fBpvcreate\fP(8)) "/dev/sda4" and "/dev/sdn1".
