12 vgextend allows you to add one or more initialized physical volumes ( see
14 ) to an existing volume group to extend it in size.
16 If \fIPhysicalDevicePath\fP was not previously configured for LVM with
17 \fBpvcreate (8)\fP, the device will be initialized with the same
18 default values used with \fBpvcreate\fP. If non-default
19 \fPpvcreate\fP values are are desired, they may be given on the
20 commandline with the same options as \fPpvcreate\fP. See
21 \fBPHYSICAL DEVICE OPTIONS\fP for available options. Note
22 that the restore-related options such as --restorefile, --uuid,
23 and --physicalvolumesize are not available. If a restore operation
24 is needed, use \fBpvcreate (8)\fP and \fBvgcfgrestore (8)\fP.
26 See \fBlvm\fP for common options.
27 .SH PHYSICAL DEVICE OPTIONS
