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 KV store of a node of a cluster of a distributed storage management system manages storage of data blocks as values and corresponding block IDs as keys. Data integrity errors are reported to the first node in the form of a list of missing block IDs that are in use but missing from the KV store. A metadata resynchronization process may then be caused to be performed, including for each block ID in the list of missing block IDs: (i) reading a data block corresponding to the block ID from another 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 node.
