Abstract
Systems and methods that make use of cluster-level redundancy within a distributed storage system to address various node-level error scenarios are provided. Rather than making use of a generalized one-size-fits-all approach in an effort to reduce complexity, an approach tailored to the node-level error scenario at issue may be performed to avoid doing more than necessary. According to one embodiment, responsive to identification of a failed RAID stripe by a node of a cluster of a distributed storage management system, for each block ID of multiple block IDs associated with the failed RAID stripe, a data block is restored corresponding to the block ID by reading the data block from another node of the cluster having a redundant copy of the data block; and writing the redundant copy of the data block to a storage area of the node that is unaffected by the failed RAID stripe.
