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:

              • 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  volume  it  is
       associated with:

       lvdisplay vg00/snapshot
