       pvdisplay [-c|--colon] [-d|--debug] [-h|--help] [-s|--short] [-v[v]|--verbose [--verbose]] PhysicalVolumePath [PhysicalVolumePath...]

DESCRIPTION

       pvdisplay allows you to see the attributes of one or more physical volumes like size, physical extent size, space used for the volume group
       descriptor area and so on.

   OPTIONS
       -c, --colon

	      * physical volume device name
	      * volume group name
	      * physical volume size in kilobytes
	      * internal physical volume number
	      * physical volume status
	      * physical volume (not) allocatable
	      * current number of logical volumes on this physical volume
	      * physical extent size in kilobytes
