Cohorts may be created on storage nodes in an object-redundant storage system that uses replication and/or a redundant encoding technique. In a cohort with N nodes, M data elements (replicas or shards) of an object are stored to M of the nodes that are selected from the N nodes. Metadata for locating other data elements for an object in the cohort may be stored with one or more of the data elements in the cohort. To reconcile the nodes, common object lists are generated on each node for at least one other node from the metadata, hashes of the lists may be exchanged among the nodes, and the hashes are compared. If the hashes for two nodes differ, specific differences are determined, and a reconciliation process performs reconciliation based on the determined differences. |
