Abstract
Example redundant array of independent disks (RAID) storage systems and methods provide rebuild of logical data groups in priority order. Storage devices are configured as a storage array for storing logical data groups distributed among the storage devices. The logical data groups are written in a configuration of RAID stripes in the storage devices. A logical group index includes a logical group map for each logical data group and identifies corresponding logical blocks. When a storage device fails, the rebuild queue is ordered based on the priority of the logical data groups and rebuild to the replacement storage device is completed in the priority order.
