Fast recovery of synchronous replication to minimize disruption in a cross-site distributed storage system

A multi-site distributed storage system having a primary storage site with a primary storage cluster and a secondary storage site with a secondary storage cluster, comprising:

• one or more processing resources;
• and
• a non-transitory computer-readable medium coupled to the one or more processing resources, having stored therein instructions, which when executed by the one or more processing resources cause the one or more processing resources to:
• establish synchronous replication between one or more storage objects of a first consistency group (CG1) of a primary storage site and one or more storage objects of a second consistency group (CG2) of a secondary storage site with at least one storage site having read/write access;
• and
• initiate a peer health check to determine a health condition of the primary storage site and concurrently initiate a create snapshot process to create a snapshot of one or more storage objects of the CG2 of the secondary storage site in response to detection of missing heartbeat communications from the primary storage site, wherein the snapshot of the one or more storage objects of the CG2 is utilized to reduce a time for transitioning from out of sync state to in sync state when the out of sync state occurs between the one or more storage objects of CG1 and the one or more storage objects of CG2.
