lvscan - scan (all disks) for logical volumes lvscan [ -a | --all] [ -b | --blockdevice ] [ -d | --debug ] [ -h | --help ] [ --ignorelockingfailure ] [ -P | --partial ] [ -v | --verbose ] lvscan scans all known volume groups or all supported LVM block devices in the system for defined logical volumes. 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 Adds the device major and minor numbers to the display of each logical volume.
