LVSCAN(8)                            System Manager's Manual                            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] [-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 indicat‐
       ing 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  compo‐
              nents  of  normally-accessible  Logical Volumes, such as mirrors, but which are not
              independently accessible (e.g. not mountable).  For example, after creating a  mir‐
              ror  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 phys‐
              ical volume availability. This is only necessary if the logical volume is not being
              monitored by dmeventd (see lvchange(8), option --monitor).
