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 is recommended over
lvdisplay.
OPTIONS¶
See
lvm 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, --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.
- --columns | -C
- Display output in columns, the equivalent of lvs.
Options listed are the same as options given in lvs (8).
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.
