vgcreate and vgextend now implicitly call pvcreate on devices not currently initialized for LVM use. Previously these commands would fail with an error, so clarify the new behavior in the man page.

|
|
.B pvcreate(8)
|
|
) to an existing volume group to extend it in size.

|
|
If \fIPhysicalDevicePath\fP was not previously configured for LVM with
|
|
\fBpvcreate (8)\fP, the device will be initialized with the same
|
|
default values used with \fBpvcreate\fP. If non-default
|
|
\fPpvcreate\fP values are are desired, they may be given on the
|
|
commandline with the same options as \fPpvcreate\fP. See
|
|
\fBPHYSICAL DEVICE OPTIONS\fP 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 \fBpvcreate (8)\fP and \fBvgcfgrestore (8)\fP.
|
|
\fBpvcreate (8)\fP, the device will be initialized with the same
|
|
default values used with \fBpvcreate\fP. If non-default
|
|
\fPpvcreate\fP values are are desired, \fBpvcreate\fP should be explicitly
|
|
called prior to calling \fBvgcreate\fP.
|
|
.SH OPTIONS
|
|
See \fBlvm\fP for common options.

.SH PHYSICAL DEVICE OPTIONS
