1. A computer-implemented method comprising: after receiving policy information that indicates criteria for volume caching operations in a storage system cluster, determining attribute information of nodes in the storage system cluster, wherein the criteria comprises node attributes, operational events, and a cached volume configuration; determining, in relation to a first node, that the criteria indicated by the received policy information are satisfied based, at least in part, upon the determined attribute information; determining, in relation to a second node, that the criteria indicated by the received policy information are satisfied based, at least in part, upon the determined attribute information; requesting that the first node of the nodes perform a first volume caching operation responsive to determining that the criteria relating to the first node are satisfied based, at least in part, on the attribute information for the first node; and requesting that the second node of the nodes perform a second volume caching operation responsive to determining that the criteria relating to the second node are satisfied based, at least in part, on the attribute information for the second node.
