Coercion
Coercion is the process of rounding down the number of Logical blocks used for the physical members of a virtual disk to a common number. This allows drives with different absolute capacities, which can vary between drive manufacturers and drive families, to share a common stripe size and count as members of the virtual disk. Coercion necessarily results in a smaller capacity than was available on the
