NAME
lvdisplay - display attributes of a logical volume
SYNOPSIS
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 com- plete path. See also lvm(8), lvcreate(8), lvscan(8), lvmsadc(8), lvmsar(8)
