lvdisplay − display attributes of a logical volume
lvdisplay [−c/−−colon] [−d/−−debug] [−h/−?/−−help] [−−ignorelockingfailure] [−−maps] [−P/−−partial] [−v/−−verbose] LogicalVolumePath [LogicalVolumePath...]
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).
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.
"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.
