1. A method performed by one or more processing resources of one or more computer systems, the method comprising:
receiving a data packet via a network at a processing resource within a first of a plurality of nodes from a second of the plurality of nodes within a cluster switch fabric;
processing the data packet, at the processing resource, to retrieve a request to perform changes to one or more compliance configuration settings stored in a root constituent of a group of flexible volumes storing compliance data, wherein the group of flexible volumes is distributed among the plurality of nodes;
deleting, at the processing resource, a configuration cache file stored within a cache at each of a plurality of non-root constituents of the group of flexible volumes, wherein the configuration cache file indicates whether a constituent is currently storing valid compliance configuration settings associated with a compliance clock used to determine a retention period of the group of flexible volumes;
applying, at the processing resource, the compliance configuration settings at the root constituent; and
storing, at the processing resource, the changed compliance configuration settings.
