Claim 21:
22. A non-transitory computer-readable storage medium embodying a set of instructions, which when executed by a processing resource of node of a plurality of nodes of a cluster representing a distributed storage system, cause the node to:
for each volume of a set of volumes owned by the node and representing a member of a local consistency group (CG), maintain an entry within a cache of the node containing volume-level CG relationship information for the volume and a peered volume representing a member of a remote CG of a remote cluster, wherein the volume-level CG relationship information identifies the volume as either a source or a destination of data replication with respect to the peered volume; and
responsive to receipt by the node of an add volume event for a first volume, add a passive cache entry, containing the volume-level CG relationship information for the first volume, to the cache, wherein the node represents a non-high-availability (HA) partner node of an original node of the plurality of nodes from which the first volume is being relocated or an HA partner node of the non-HA partner node.
