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 vol-
	      ume is not being monitored by dmeventd (see lvchange(8),	option
	      --monitor).
