.SH DESCRIPTION
lvdisplay allows you to see the attributes of a logical volume
like size, read/write status, snapshot information etc.
2004-11-12 18:59:09 +03:00
.P
2012-04-11 16:42:10 +04:00
\fB lvs\fP (8) is an alternative that provides the same information
in the style of \fB ps\fP (1).
\fB lvs\fP (8) is recommended over \fB lvdisplay\fP .

2002-01-04 23:35:19 +03:00
.SH OPTIONS
2012-04-11 16:42:10 +04:00
See \fB lvm\fP (8) for common options and \fB lvs\fP for options given with
2009-10-26 17:37:09 +03:00
\fB \- \- columns\fP .

2012-04-11 16:42:10 +04:00
.B \- \- all
2009-10-26 17:37:09 +03:00
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).
2012-04-11 16:42:10 +04:00
For example, after creating a mirror using
\fB lvcreate \- m1 \- \- mirrorlog disk\fP ,
2009-10-26 17:37:09 +03:00
this option will reveal three internal Logical Volumes, with suffixes
mimage_0, mimage_1, and mlog.

.BR \- c ", " \- \- colon
2002-11-18 17:04:08 +03:00
Generate colon separated output for easier parsing in scripts or programs.
2012-04-11 16:42:10 +04:00
N.B. \fB lvs\fP (8) provides considerably more control over the output.
2002-01-04 23:35:19 +03:00
.nf
The values are:
* logical volume name
* volume group name
* logical volume access
* logical volume status
* internal logical volume number
* open count of logical volume
2007-07-24 14:58:01 +04:00
* logical volume size in sectors
2002-01-04 23:35:19 +03:00
* 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

2012-04-11 16:42:10 +04:00
to logical extents use:

Display output in columns, the equivalent of \fB lvs\fP . Options listed
are the same as options given in \fB lvs\fP (8).

.SH Examples
2012-04-11 16:42:10 +04:00
Shows attributes of that logical volume. If snapshot
2002-01-04 23:35:19 +03:00
logical volumes have been created for this original logical volume,
this command shows a list of all snapshot logical volumes and their
2012-04-11 16:42:10 +04:00
status (active or inactive) as well:
.sp

2002-01-04 23:35:19 +03:00
2012-04-11 16:42:10 +04:00
Shows the attributes of this snapshot logical volume and also which
original logical volume it is associated with:
.sp
.B lvdisplay /dev/vg00/snapshot
