lvdisplay(8) -- Linux man page



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 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.
