B.5.1. Linear
A Linear-RAID region can be expanded in two ways. First, if the last child object in the Linear-RAID region is expandable, then that object can be expanded, and the RAID region can expand into that new space. Second, one or more new objects can be added to the end of the region.
Likewise, a Linear-RAID region can be shrunk in two ways. If the last child object in the region is shrinkable, then that object can be shrunk, and the RAID region will shrink by the same amount. Also, one or more objects can be removed from the end of the RAID region (but the first object in the region cannot be removed).
Linear-RAID regions can be resized while they are active and in use.
