Abstract
A distributed storage system replicates data for a primary logical storage object on a primary node of the storage system to a secondary logical storage object on a secondary node on the distributed storage system. Failures in writing data to the primary logical storage object or failures in the replication of the data to the secondary logical storage object can cause data that should be synchronized to become divergent. In cases where the data may be divergent, reconciliation operations can be performed to resynchronize the data.
