LVDISPLAY(8)			     System Manager's Manual			     LVDISPLAY(8)

NAME
       lvdisplay - display attributes of a logical volume

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

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

   OPTIONS
       -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
	      active.

       -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.

Examples
       "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.

DIAGNOSTICS
       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

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