SYNOPSIS
lvdisplay
[-c|--colon] [-d|--debug] [-h|-?|--help]

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 is recommended over
lvdisplay.
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 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.
Examples
"lvdisplay -v /dev/vg00/lvol2" 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 /dev/vg00/snapshot" shows the attributes of this snapshot
logical volume and also which original logical volume
it is associated with.
