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
