Abstract
A predictable distribution of protection group members and spares in compliance with RAID requirements is maintained as a drive cluster is scaled-up and eventually split into multiple clusters. Conditions under which addition of new disks using rotation-relocation and cell borrowing would create recurrent patterns of distribution of protection group members are recognized and the associated groups of disks are index-swapped to reduce the amount of data and parity information that needs to be relocated.
