NAME

6       lvscan — scan (all disks) for Logical Volumes
7

SYNOPSIS

9       lvscan  [-a|--all]  [-b|--blockdevice]  [--commandprofile  ProfileName]
10       [-d|--debug]   [-h|--help]   [--ignorelockingfailure]    [-P|--partial]
11       [-v|--verbose]
12

DESCRIPTION

14       lvscan scans all known volume groups or all supported LVM block devices
15       in the system for defined Logical Volumes.  The output consists of  one
16       line  for each Logical Volume indicating whether or not it is active, a
17       snapshot or origin, the size of the device and its  allocation  policy.
18       Use  lvs(8)  or  lvdisplay(8)  to obtain more-comprehensive information
19       about the Logical Volumes.

OPTIONS

22       See lvm(8) for common options.
23
24       --all  Include information in the output about internal Logical Volumes
25              that are components of normally-accessible Logical Volumes, such
26              as mirrors, but which are not independently accessible (e.g. not
27              mountable).  For example, after creating a mirror using lvcreate
28              -m1 --mirrorlog disk, this option  will  reveal  three  internal
29              Logical Volumes, with suffixes mimage_0, mimage_1, and mlog.
30
31       -b, --blockdevice
32              This option is now ignored.  Instead, use lvs(8) or lvdisplay(8)
33              to obtain the device number.
34
35       --cache LogicalVolume
36              Applicable only when lvmetad(8) is in use (see also lvm.conf(5),
37              global/use_lvmetad).  This  command  issues a rescan of physical
38              volume labels and metadata areas of all  PVs  that  the  logical
39              volume uses. In particular, this can be used when a RAID logical
40              volume becomes degraded, to update  information  about  physical
41              volume  availability. This is only necessary if the logical vol‐
42              ume is not being monitored by dmeventd (see lvchange(8),  option
43              --monitor).
