LVM does not use unpartitioned space for anything TTBOMK. It uses
physical volumes (PVs) which are block devices (either partitions or
whole disks or RAID arrays etc.). These are entirely self-contained.
Internally, the PV contains its own metadata and extents which are
allocated to individual logical volumes within the volume group
containing the PV. It's simply impractical and fragile to use
unpartitioned space, and LVM only uses the devices (partitions) you
put the PVs on.
