ABSTRACT:
Methods and associated structure to improve disk capacity utilization in the context of size coercion and COD space reservation techniques applied in a storage system. One aspect hereof provides that the size coercion computations to reduce (round down) the capacity of one or more disk drives in a storage system are performed prior to reservation of disk space for use in configuration-on-disk (COD) techniques. Performing coercion computations and configuration prior to COD space reservation prevents the COD reservation processing from causing un-necessary waste of physical capacity of the coerced disk drives.
