摘要:
Provided are a method, system, and article of manufacture, wherein a plurality of nodes coupled over a network are maintained, wherein a first node of the plurality of nodes initially owns a plurality of storage objects accessible via the network. A second node preemptively takes ownership of a selected storage object of the plurality of storage objects, in response to the first node becoming unavailable, wherein other nodes of the plurality of nodes can request ownership of the selected storage object while the first node is unavailable. A determination is made that the first node that originally owned the selected storage object has become available after a period of unavailability. A determination is made of the current owner node of the selected storage object, wherein the current owner node is one of the second node and the other nodes. The selected storage object is updated at the first node by the current owner node of the selected storage object, prior to allowing the first node to act on or assume ownership of the selected storage object.
