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).
