Claim 0:
1. A computer implemented method performed by one or more processing resources of a storage node, the method comprising:
maintaining state information regarding a data replication status for a storage object of the storage node of a primary storage cluster with the storage object being replicated to a replicated storage object of a secondary storage cluster;
temporarily disallowing input/output (I/O) operations for the storage object when the storage object of the primary storage cluster has a connection loss or failure, which causes an out of sync (OOS) state for the storage object of the primary storage cluster;
initiating a resynchronization between the storage object and the replicated storage object based on the OOS state with the resynchronization including initiating asynchronous inflight tracking and replay of any missing I/O operations that are missing from one of a first Op log of the primary storage cluster and a second Op log of the secondary storage cluster; and
allowing new I/O operations to be handled with the storage object of the primary storage cluster without waiting for completion of the asynchronous inflight tracking and replay at the secondary storage cluster.
