Abstract
In one embodiment, a method comprises 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 when the storage object has a connection loss or failure. The method further includes initiating a resynchronization between the storage object and the replicated storage object including initiating asynchronous persistent 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 persistent inflight tracking and replay at the secondary storage cluster.
