Abstract
Techniques detect non-uniform distributions of RAID extents across the storage drives of a data storage appliance and rebalance the allocation of disk extents of the storage drives amongst the RAID extents. The improved techniques prevent the distribution of RAID extents across the storage drives of a mapped RAID system from becoming overly non-uniform.
