Abstract:
Implementations described herein generally provide methods, systems and media for recovering data from disk failures. One method generally includes calculating a global parity for a group of disks comprising multiple independent RAID (Redundant Array of Independent Disks) arrays; determining if a two disk failure has occurred within a single RAID array; and if so, recovering from the two disk failure using the global parity and data from the RAID arrays.
