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(8) is recommended over lvdisplay.
OPTIONS
See lvm(8) for common options and lvs for options given with --columns. --all Include information in the output about internal Logical Volumes that are components of normally-accessible Logical Volumes, such as mirrors, but which are not independently accessible (e.g. not mountable). For example, after creating a mirror using lvcreate -m1 --mirrorlog disk, this option will reveal three internal Logical Volumes, with suffixes mimage_0, mimage_1, and mlog. -C, --columns Display output in columns, the equivalent of lvs(8). Options listed are the same as options given in lvs(8). -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. To map physical extents to logical extents use: pvs --segments -o+lv_name,seg_start_pe,segtype
Examples
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 -v vg00/lvol2 Shows the attributes of this snapshot logical volume and also which original logical volume it is associated with: lvdisplay vg00/snapshot
