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.
--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.
