.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
