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
