SYNOPSISlvdisplay [-c/--colon] [-d/--debug] [-h/-?/--help] [--ignorelockingfailure] [--maps] [-P/--partial] [-v/--verbose] LogicalVolumePath [LogicalVolumePath...]
DESCRIPTIONlvdisplay 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).
OPTIONSSee 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.
