Abstract: Methods and apparatus, including computer program products, implementing and using techniques for data replication in a cluster. In response to identifying data to replicate in a multi-node system by a first node in a cluster, the data is written concurrently to other nodes in the cluster based on a rule set in a repository. In response to detecting a criterion described in the rule set, an action is performed.

Abstract: Provided are techniques for movement readiness checking. It is determined whether each content object in a set of content objects is ready for movement. For each content object in the set of content objects that is determined to be ready for movement, an associated movement readiness indicator is set to indicate that the content object is ready to be moved. Then, each content object in the set of content objects is moved that has the associated movement readiness indicator set to indicate that the content object is ready to be moved.

Abstract: A controller receives a request from a user to store content in a target node of a plurality of nodes. A determination is made of a preferred node for the user, from a repository that maintains a correspondence between the user and the preferred node for storing the content for the user, wherein the preferred node is included in the plurality of nodes. Responsive to determining from that the determined preferred node is the target node, the controller transmits the request from the user to store the content, to the preferred node. Responsive to determining that the determined preferred node is not the target node, the controller transmits the request and an identification of the target node to the preferred node.
