.SH DESCRIPTION
|
||
|
.B pvcreate
|
||
|
initializes
|
||
|
.I PhysicalVolume
|
||
|
for later use by the Logical Volume Manager (LVM). Each
|
||
|
.I PhysicalVolume
|
||
|
can be a disk partition, whole disk, meta device, or loopback file.
|
||
|
For DOS disk partitions, the partition id must be set to 0x8e using
|
||
|
.BR fdisk "(8), " cfdisk "(8), "
|
||
|
or a equivalent. For
|
||
|
.B whole disk devices only
|
||
|
the partition table must be erased, which will effectively destroy all
|
||
|
data on that disk. This can be done by zeroing the first sector with:
|
||
|
.sp
|
||
|
.BI "dd if=/dev/zero of=" PhysicalVolume " bs=512 count=1"
|
||
|
.sp
|
||
|
Continue with
|
||
|
.BR vgcreate (8)
|
||
|
to create a new volume group on
|
||
|
.IR PhysicalVolume ,
|
||
|
or
|
||
|
.BR vgextend (8)
|
||
|
to add
|
||
|
.I PhysicalVolume
|
||
|
to an existing volume group.
|
||
|
.SH OPTIONS
|
||
|
See \fBlvm\fP for common options.
|
||
|
.TP
|
||
|
.BR \-f ", " \-\-force
|
||
|
Force the creation without any confirmation. You can not recreate
|
||
|
(reinitialize) a physical volume belonging to an existing volume group.
|
||
|
In an emergency you can override this behaviour with -ff. In no case
|
||
|
case can you initialize an active physical volume with this command.
|
||

.BR \-y ", " \-\-yes
|
||
|
Answer yes to all questions.
|

|
.SH Example
|

Initialize partition #4 on the third SCSI disk and the entire fifth
|
||
|
SCSI disk for later use by LVM:
|

.B pvcreate /dev/sdc4 /dev/sde
