SYNOPSIS

lvdisplay [-c/--colon] [-d/--debug] [-h/-?/--help] [--ignorelockingfailure] [--maps] [-P/--partial] [-v/--verbose] LogicalVolumePath [LogicalVolumePath...]

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).

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. 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.
