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) .
OPTIONS
See lvm for common options.
-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 kilobytes
* 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.
Examples
"lvdisplay -v /dev/vg00/lvol2" shows attributes of that logical volume
and its mapping of logical to physical extents. In case 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 /dev/vg00/snapshot" shows the attributes of this snapshot
logical volume and also which original logical volume
it is associated with.
