LVSCAN(8) System Manager's Manual LVSCAN(8)
NAME
lvscan - scan (all disks) for Logical Volumes
SYNOPSIS
lvscan [-a|--all] [-b|--blockdevice] [-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 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.
