NAME

       lvscan — scan (all disks) for Logical Volumes

SYNOPSIS

       lvscan    [-a|--all]   [-b|--blockdevice]   [--commandprofile   ProfileName]   [-d|--debug]   [-h|--help]
       [--ignorelockingfailure] [-P|--partial] [-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).
