CVS functions (Volume to Space, Install CV, Volume Initialize, and Make Volume) are performed on
each VDEV. VDEVs are also separated from each other by the boundary limitation. Therefore, you
cannot define a volume across two or more VDEVs beyond the boundaries.

As the result of CVS operations, a VDEV contains FVs, CVs, and free spaces that are delimited in
logical cylinders. Sequential free spaces are combined into a single free space (see Figure 80).

This function converts one or more LDEVs (FVs or CVs) into free space, which deletes the selected
LDEVs from that VDEV.
