       lvdisplay - display attributes of a logical volume

       lvdisplay  [-c|--colon] [-d|--debug] [-D|--disk] [-h|--help] [-v[v]|--verbose] LogicalVol-
       umePath [LogicalVolumePath...]

       lvdisplay allows you to see the attributes of a logical volume like size, read/write  sta-
       tus, snapshot information etc.

       -c, --colon
	      Generate colon seperated output for easier parsing in scripts or programs.

	      The values are:

	      * logical volume name
	      * volume group name
	      * logical volume access
	      * logical volume status
	      * internal logical volume number
	      * open count of logical volume
	      * logical volume size in kilobytes
	      * current logical extents associated to logical volume
	      * allocated logical extents of logical volume
	      * allocation policy of logical volume
	      * read ahead sectors of logical volume
	      * major device number of logical volume
	      * minor device number of logical volume

       -d, --debug
	      Enables additional debugging output (if compiled with DEBUG).

       -D, --disk
	      Show  attributes	of  the  volume  group descriptor array on disk(s).  Without this
	      switch they are derived from kernel space.   Useful,  if	the  volume  group  isn't

       -h, --help
	      Print a usage message on standard output and exit successfully.

       -v, --verbose
	      Display the mapping of logical extents to physical volumes and physical extents.

       -vv, --verbose --verbose
	      Like -v with verbose runtime information.

       "lvdisplay  -v /dev/vg00/lvol2" shows attributes of that logical volume and its mapping of
       logical to physical extents. In case snapshot logical volumes have been created	for  this
       original  logical  volume,  this  command shows a list of all snapshot logical volumes and
       their status (active or inactive) as well.

       "lvdisplay /dev/vg00/snapshot" shows the attributes of this snapshot  logical  volume  and
       also which original logical volume it is associated with.

       lvdisplay returns an exit code of 0 for success or > 0 for error:

       1  no logical volume name(s) on command line

       95 driver/module not in kernel
       96 invalid I/O protocol version
       97 error locking logical volume manager
       98 invalid lvmtab (run vgscan(8))
       99 invalid command line

	      The  default  Volume  Group Name to use. Setting this variable enables you to enter
	      just the Logical Volume Name rather than its complete path.
