DESCRIPTION

24       lvdisplay  allows  you  to  see the attributes of a logical volume like
25       size, read/write status, snapshot information etc.
26
27       lvs(8) is an alternative that provides  the  same  information  in  the
28       style of ps(1).  lvs(8) is recommended over lvdisplay.

OPTIONS

32       See lvm(8) for common options and lvs for options given with --columns.
33
34       --all  Include information in the output about internal Logical Volumes
35              that are components of normally-accessible Logical Volumes, such
36              as mirrors, but which are not independently accessible (e.g. not
37              mountable).  For example, after creating a mirror using lvcreate
38              -m1  --mirrorlog  disk,  this  option will reveal three internal
39              Logical Volumes, with suffixes mimage_0, mimage_1, and mlog.
40
41       -C, --columns
42              Display output in columns, the equivalent  of  lvs(8).   Options
43              listed are the same as options given in lvs(8).
44
45       -c, --colon
46              Generate colon separated output for easier parsing in scripts or
47              programs.  N.B. lvs(8) provides considerably more  control  over
48              the output.
49
50              The values are:
51
52              · logical volume name
53              · volume group name
54              · logical volume access
55              · logical volume status
56              · internal logical volume number
57              · open count of logical volume
58              · logical volume size in sectors
59              · current logical extents associated to logical volume
60              · allocated logical extents of logical volume
61              · allocation policy of logical volume
62              · read ahead sectors of logical volume
63              · major device number of logical volume
64              · minor device number of logical volume
65
66
67       -m, --maps
68              Display  the  mapping of logical extents to physical volumes and
69              physical extents.  To map physical extents  to  logical  extents
70              use: pvs --segments -o+lv_name,seg_start_pe,segtype
71

Examples

73       Shows  attributes  of  that logical volume. If snapshot logical volumes
74       have been created for this original logical volume, this command  shows
75       a  list  of  all  snapshot  logical volumes and their status (active or
76       inactive) as well:
77
78       lvdisplay -v vg00/lvol2
79
80       Shows the attributes of this snapshot logical  volume  and  also  which
81       original logical volume it is associated with:
82
83       lvdisplay vg00/snapshot
84
85
