Abstract
OP logs are utilized for fast recovery of synchronous replication in a storage system. According to one embodiment, a computer-implemented method comprises establishing 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, initiating a peer health check to determine a health condition of the primary storage site and concurrently initiating 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, and performing inflight tracking replay and reconciliation between a first Op log of the primary storage site and a second Op log of the secondary storage site when an out of sync state or failover occurs.
