NAME
lvdisplay - display attributes of a logical volumeSYNOPSIS
lvdisplay [-c|--colon] [-d|--debug] [-D|--disk] [-h|--help] [-v[v]|--verbose] LogicalVolumePath [LogicalVolumePath...]DESCRIPTION
lvdisplay allows you to see the attributes of a logical volume like size, read/write status, snapshot information etc.OPTIONS
- -c, --colon
-
Generate colon seperated output for easier parsing in scripts or programs.
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 kilobytes * 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
- -d, --debug
- Enables additional debugging output (if compiled with DEBUG).
- -D, --disk
- Show attributes of the volume group descriptor array on disk(s). Without this switch they are derived from kernel space. Useful, if the volume group isn't active.
- -h, --help
- Print a usage message on standard output and exit successfully.
- -v, --verbose
- Display the mapping of logical extents to physical volumes and physical extents.
- -vv, --verbose --verbose
- Like -v with verbose runtime information.
Examples
"lvdisplay -v /dev/vg00/lvol2" shows attributes of that logical volume and its mapping of logical to physical extents. In case 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.
DIAGNOSTICS
lvdisplay returns an exit code of 0 for success or > 0 for error:1 no logical volume name(s) on command line 95 driver/module not in kernel 96 invalid I/O protocol version 97 error locking logical volume manager 98 invalid lvmtab (run vgscan(8)) 99 invalid command line
ENVIRONMENT VARIABLES
- LVM_VG_NAME
-
The default Volume Group Name to use. Setting this variable enables
you to enter just the Logical Volume Name rather than its complete path.
