scans all known volume groups or all supported LVM block devices
in the system for defined logical volumes.
See lvm for common options.
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.
Adds the device major and minor numbers to the display
of each logical volume.
