lvscan(8)
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).
