Abstract:
Systems and methods that make use of cluster-level redundancy within a distributed storage management system to address various node-level error scenarios are provided. According to one embodiment, a first node of multiple nodes of distributed storage system represented in a form of a cluster of the multiple of nodes, identifies the potential existence of an error associated with a Redundant Array of Independent Disks (RAID) stripe. A list of block identifiers (IDs) associated with the RAID stripe may then be identified. Rather than performing a traditional RAID recovery/reconstruction approach that is resource intensive in nature and that requires an excessive amount of rebuild time, a more efficient RAID stripe resynchronization process may be performed to restore data associated with the RAID stripe.
