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

       lvs(8)  is  an  alternative  that  provides the same information in the
       style of ps(1).	lvs(8) is recommended over lvdisplay.


OPTIONS
       See lvm(8) for common options and lvs for options given with --columns.

       --all  Include information in the output about internal Logical Volumes
	      that are components of normally-accessible Logical Volumes, such
	      as mirrors, but which are not independently accessible (e.g. not
	      mountable).  For example, after creating a mirror using lvcreate
	      -m1 --mirrorlog disk, this option	 will  reveal  three  internal
	      Logical Volumes, with suffixes mimage_0, mimage_1, and mlog.

       -C, --columns
	      Display  output  in  columns, the equivalent of lvs(8).  Options
	      listed are the same as options given in lvs(8).

       -c, --colon
	      Generate colon separated output for easier parsing in scripts or
	      programs.	  N.B.	lvs(8) provides considerably more control over
	      the output.

	      The values are:

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


       -m, --maps
	      Display the mapping of logical extents to physical  volumes  and
	      physical	extents.   To  map physical extents to logical extents
	      use: pvs --segments -o+lv_name,seg_start_pe,segtype

Examples
       Shows attributes of that logical volume. If  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 -v vg00/lvol2

       Shows  the  attributes  of  this snapshot logical volume and also which
       original logical volume it is associated with:

       lvdisplay vg00/snapshot
