| .SH DESCRIPTION |
| lvdisplay allows you to see the attributes of a logical volume |
| like size, read/write status, snapshot information etc. |
| .P |
| \fBlvs\fP(8) is an alternative that provides the same information |
| in the style of \fBps\fP(1). |
| \fBlvs\fP(8) is recommended over \fBlvdisplay\fP. |
| |
| .SH OPTIONS |
| See \fBlvm\fP(8) for common options and \fBlvs\fP for options given with |
| \fB\-\-columns\fP. |
| .TP |
| .B \-\-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 |
| \fBlvcreate \-m1 \-\-mirrorlog disk\fP, |
| this option will reveal three internal Logical Volumes, with suffixes |
| mimage_0, mimage_1, and mlog. |
| .TP |
| .BR \-C ", " \-\-columns |
| Display output in columns, the equivalent of \fBlvs\fP(8). |
| Options listed are the same as options given in \fBlvs\fP(8). |
| .TP |
| .BR \-c ", " \-\-colon |
| Generate colon separated output for easier parsing in scripts or programs. |
| N.B. \fBlvs\fP(8) provides considerably more control over the output. |
| .nf |
| |
| The values are: |
| |
| \(bu logical volume name |
| \(bu volume group name |
| \(bu logical volume access |
| \(bu logical volume status |
| \(bu internal logical volume number |
| \(bu open count of logical volume |
| \(bu logical volume size in sectors |
| \(bu current logical extents associated to logical volume |
| \(bu allocated logical extents of logical volume |
| \(bu allocation policy of logical volume |
| \(bu read ahead sectors of logical volume |
| \(bu major device number of logical volume |
| \(bu minor device number of logical volume |
| |
| .fi |
| .TP |
| .BR \-m ", " \-\-maps |
| Display the mapping of logical extents to physical volumes and |
| physical extents. To map physical extents |
| to logical extents use: |
| .B pvs \-\-segments \-o+lv_name,seg_start_pe,segtype |
| .SH 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: |
| .sp |
| .B lvdisplay \-v vg00/lvol2 |
| |
| Shows the attributes of this snapshot logical volume and also which |
| original logical volume it is associated with: |
| .sp |
| .B lvdisplay vg00/snapshot |
