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. Rather than using a generalized one-size-fits-all approach 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 identifying a missing branch of a tree implemented by a KV store of a first node of a cluster of a distributed storage management system, a branch resynchronization process may be performed, including, for each block ID in the range of block IDs of the missing branch (i) reading a data block corresponding to the block ID from a second node of the cluster that maintains redundant information relating to the block ID; and (ii) restoring the block ID within the KV store by writing the data block to the first node.
