 +
 +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 Vol‐
 +              umes, 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 mim‐
 +              age_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
 +
