22 lvdisplay allows you to see the attributes of a logical volume like
23 size, read/write status, snapshot information etc.
24
25 lvs (8) is an alternative that provides the same information in the
26 style of ps (1). lvs is recommended over lvdisplay.
27
28
30 See lvm for common options and lvs for options given with --columns.
31
32 --all Include information in the output about internal Logical Volumes
33 that are components of normally-accessible Logical Volumes, such
34 as mirrors, but which are not independently accessible (e.g. not
35 mountable). For example, after creating a mirror using 'lvcre‐
36 ate -m1 --mirrorlog disk', this option will reveal three inter‐
37 nal Logical Volumes, with suffixes mimage_0, mimage_1, and mlog.
38
39 -c, --colon
40 Generate colon separated output for easier parsing in scripts or
41 programs. N.B. lvs (8) provides considerably more control over
42 the output.
43
44 The values are:
45
46 * logical volume name
47 * volume group name
48 * logical volume access
49 * logical volume status
50 * internal logical volume number
51 * open count of logical volume
52 * logical volume size in sectors
53 * current logical extents associated to logical volume
54 * allocated logical extents of logical volume
55 * allocation policy of logical volume
56 * read ahead sectors of logical volume
57 * major device number of logical volume
58 * minor device number of logical volume
59
60
61 -m, --maps
62 Display the mapping of logical extents to physical volumes and
63 physical extents. To map physical extents to logical extents
64 use pvs --segments -o+lv_name,seg_start_pe,segtype.
65
66 --columns | -C
67 Display output in columns, the equivalent of lvs. Options
68 listed are the same as options given in lvs (8).
69
71 "lvdisplay -v /dev/vg00/lvol2" shows attributes of that logical volume.
72 If snapshot logical volumes have been created for this original logical
73 volume, this command shows a list of all snapshot logical volumes and
74 their status (active or inactive) as well.
75
76 "lvdisplay /dev/vg00/snapshot" shows the attributes of this snapshot
77 logical volume and also which original logical volume it is associated
78 with.
