Claim 12:
13. A cluster of a plurality of nodes collectively representing a distributed storage system, the cluster comprising:
one or more processing resources; and
one or more non-transitory computer-readable media, coupled to the one or more processing resources, having stored therein instructions that when executed by the one or more processing resource cause the cluster to:
responsive to a disruptive operation affecting a status of data replication between a peered pair of volumes, including a first volume of a set of volumes of a first node of the plurality of nodes and a second volume of a second node of a remote cluster, determine whether the disruptive operation represents a first scenario involving a relocation of the first volume from the first node to a high-availability (HA) partner node within the cluster or a second scenario involving a relocation of the first volume from the first node to a non-HA partner node within the cluster;
responsive to the first scenario, facilitate resynchronization of the data replication by converting an existing passive cache entry containing information indicative of the peered pair of volumes within a cache of the HA partner node to an active cache entry; and
responsive to the second scenario, prior to the first volume coming online in the non-HA partner node, create a new passive cache entry containing the information indicative of the peered pair of volumes within a cache of the non-HA partner node.
