lvscan -- scan (all disks) for Logical Volumes
lvscan [-a|--all]
[-b|--blockdevice] [--commandprofile ProfileName] [-d|--debug] [-h|--help] [--ignorelockingfailure]
[-P|--partial] [-v|--verbose]
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.
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).
