Abstract:
A system for replicating a filesystem running on multiple nodes comprising an originator system and a replica system. The originator system includes a plurality of nodes. The replica system includes a plurality of nodes and a processor. The plurality of nodes of the replica system are paired with the plurality of nodes of the originator system. The processor is configured to receive an indicator of a node of the plurality of nodes of the replica system finishing replication for a view of a filesystem at a point in time. The processor is further configured to indicate that replication for the view of the filesystem is complete in the event that all replica system nodes have received their indication for the view.
