1. A method comprising: tracking generations of a first node of a plurality of nodes in a cluster that hosts a distributed redirect-on-write clustered filesystem, wherein the plurality of nodes are managing a plurality of filesets in the distributed redirect-on-write clustered filesystem and wherein the generations of the first node represent progression of consistency snapshots by the first node; and independently tracking generations for each of the plurality of filesets in the distributed redirect-on-write clustered filesystem, wherein management of the plurality of filesets is distributed across the plurality of nodes in the cluster that hosts the distributed redirect-on-write clustered filesystem, wherein the generations for each of the plurality of filesets represent progression of consistency snapshots of the plurality of filesets.
