NAME¶
lvscan — scan (all disks) for Logical Volumes
SYNOPSIS¶
lvscan [-a|--all] [-b|--blockdevice]
[--commandprofile ProfileName] [-d|--debug]
[-h|--help] [--ignorelockingfailure]
[-P|--partial] [--reportformat
{basic|json}] [-v|--verbose]
DESCRIPTION¶
lvscan scans all known volume groups or all supported LVM block devices in the
system for defined Logical Volumes. The output consists of one line for each
Logical Volume indicating whether or not it is active, a snapshot or origin,
the size of the device and its allocation policy. Use lvs(8) or
lvdisplay(8) to obtain more-comprehensive information about the Logical
Volumes.
OPTIONS¶
See lvm(8) for common options.
- --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.
- -b, --blockdevice
- This option is now ignored. Instead, use lvs(8) or
lvdisplay(8) to obtain the device number.
- --cache LogicalVolume
- Applicable only when lvmetad(8) is in use (see also
lvm.conf(5), global/use_lvmetad). This command issues a rescan of
physical volume labels and metadata areas of all PVs that the logical
volume uses. In particular, this can be used when a RAID logical volume
becomes degraded, to update information about physical volume
availability. This is only necessary if the logical volume is not
being monitored by dmeventd (see lvchange(8), option
--monitor).
