DESCRIPTION
       lvdisplay  allows you to see the attributes of a logical volume like size, read/write sta‐
       tus, 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 compo‐
              nents of normally-accessible Logical Volumes, such as mirrors, but  which  are  not
              independently  accessible (e.g. not mountable).  For example, after creating a mir‐
              ror 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:

              · 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 sectors
              · 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


       -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 vol‐
       ume it is associated with:

       lvdisplay vg00/snapshot
