Abstract: Modifying a synchronously replicated dataset, including: receiving, by a leader storage system, a request to modify a dataset that is synchronized across a plurality of storage systems; sending, from the leader storage system to a follower storage system, information describing the request to modify the dataset, wherein the leader storage system and the follower storage system each store a copy of the dataset; processing, by the leader storage system on the copy of the dataset that is stored on the leader storage system, the request to modify the dataset; receiving, from the follower storage system, an indication that the follower storage system has processed the request to modify the dataset on the copy of the dataset that is stored on the follower storage system; and acknowledging, by the leader storage system, completion of the request to modify the dataset.

Abstract: Initiating recovery actions when a dataset ceases to be synchronously replicated across a set of storage systems, including: receiving, by at least one storage system among a plurality of storage systems implementing a symmetric input/output model for a synchronously replicated dataset, a request to modify the dataset; identifying one or more operations associated with the request to modify the dataset that have not been applied to at least one storage system of the plurality of storage systems; and responsive to a system fault among the plurality of storage systems synchronously replicating the dataset, applying a recovery action based on recovery information that identifies one or more operations that have not been applied to the plurality of storage systems.

Abstract: Synchronizing snapshots between storage systems, including: receiving, from a source storage system, an identification of a snapshot to be replicated to a destination storage system, wherein the source storage system and the destination storage system are of different types; identifying, from hint information stored on the destination storage system, a most recent version of the snapshot that is stored on the destination storage system; issuing, to the source storage system, a request for an identification of the differences between the snapshot to be replicated to the destination storage system and the most recent version of the snapshot that is stored on the destination storage system; receiving, from the source storage system, the identification of the differences; and issuing a request to transfer, from the source storage system to the destination storage system, data associated with the differences.
