Abstract
New drives numbering fewer than a RAID width W are added to a primary drive array of K=W+1 sequentially-ordered original drives with same-size sequentially-ordered cells, where RAID groups are sequentially ordered and distributed such that a first cell of each sequentially-ordered drive contains a RAID group member in the sequential order of the protection groups and subsequent cells of each original drive in sequence contain members in the sequential order, wrapped. The new drives are added by selecting a subset of the original drives adjacent to the new drives such that the selected new drives and original drives total W, selecting a number of sequential cell indices equal to the number of new drives, and relocating protection group members in the selected sequential cell indices on the selected original drives to the new drives such that free space is created across W cells of each of the selected cell indices.
