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).
