A cluster system includes a plurality of computing nodes connected to a network, each node including one or more storage devices. The cluster system stores data and at least one of data replicas or erasure-coded segments across the plurality of nodes based on a redundancy policy. Further, configuration information, which may be indicative of a data placement of the data and the data replicas or erasure-coded segments on the plurality of nodes, is provided to each of the plurality of nodes. Additionally, each of the nodes may act as a first node which is configured to determine, upon a change of the redundancy policy, updated configuration information based on the change of the redundancy policy and to send a message including information indicating the change of the redundancy policy to the other nodes of the plurality of nodes.
