output.
The values are:
* physical volume device name
* volume group name
* physical volume size in kilobytes
* internal physical volume number (obsolete)
* physical volume status
* physical volume (not) allocatable
* current number of logical volumes on this physical volume
* physical extent size in kilobytes
* total number of physical extents
* free number of physical extents
* allocated number of physical extents
-s, --short
Only display the size of the given physical volumes.
