pvcreate - initialize a disk or partition for use by LVM 


pvcreate [-d|--debug] [-f[f]|--force [--force]] [-y|--yes] [-h|--help] [-v|--verbose] [-V|--versionPhysicalVolume [PhysicalVolume...] 


pvcreate initializes PhysicalVolume for later use by the Logical Volume Manager (LVM). Each 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 fdisk(8), cfdisk(8), or a equivalent. For 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:

dd if=/dev/zero of=PhysicalVolume bs=512 count=1

Continue with vgcreate(8) to create a new volume group on PhysicalVolume, or vgextend(8) to add PhysicalVolume to an existing volume group.  



Enables additional debugging output (if compiled with DEBUG).


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.


Overrides the size of the physical volume which is normally retrieved. Useful in rare case where this value is wrong. More useful to fake large physical volumes of up to 2 Terabyes - 1 Kilobyte on smaller devices for testing purposes only where no real access to data in created logical volumes is needed. If you wish to create the supported maximum, use "pvcreate -s 2147483647k PhysicalVolume [PhysicalVolume ...]". All other LVM tools will use this size with the exception of lvmdiskscan(8)
