Methods and systems to interface between a multi-site distributed storage system and an external mediator to efficiently process events related to continuity

A multi-site distributed storage system comprising:

• a processing resource;
• and
• a non-transitory computer-readable medium coupled to the processing resource, having stored therein instructions, which when executed by the processing resource cause the processing resource to:
• receive events with the events being associated with a continuity relationship for first and second clusters of the multi-site distributed storage system;
• coordinate the events including a first event that is associated with a first volume of the first cluster and other events including a second event that duplicates the first event, wherein the second event is associated with a second volume of the first cluster;
• and
• terminate any event that duplicates the first event.

A non-transitory computer-readable storage medium embodying a set of instructions, which when executed by a processing resource of a multi-site distributed storage system cause the processing resource to:

• receive events with the events being associated with a relationship for first and second clusters of the multi-site distributed storage system;
• coordinate the events including a first event of a first volume of the first cluster and other events including a second event of a second volume of the first cluster that conflicts with the first event;
• queue the events in a configuration database of the first cluster;
• and
• serialize the conflicting events across the first cluster by routing the conflicting events to the first cluster to ensure a consistent end state of the relationship.
