Abstract
An apparatus includes at least one processing device comprising a processor coupled to a memory, with the processing device being configured to maintain a synchronous replication input-output (IO) request list having a plurality of entries corresponding to respective synchronous replication IO requests, a given such entry identifying at least a sender component and one or more address locks held by the corresponding synchronous replication IO request. The processing device is further configured to detect a failure of a particular one of a plurality of sender components, to access the synchronous replication IO request list to identify one or more address locks held by at least one synchronous replication IO request previously sent by the failed sender component, and to release one or more address lock waiters that are waiting to obtain the one or more identified address locks. Other embodiments include methods and computer program products.
