The system, devices, and methods disclosed herein relate to a dynamic, robust method for choosing a “winner” in an active-active data storage network. In the systems and methods disclosed herein, two or more intelligent nodes within an active-active data storage network periodically exchange operational parameters in an ongoing negotiation regarding who should be the winner in the event of a communication failure within the network. The winner is chosen dynamically based on the operational parameters. A witness is kept apprised of the winner. In the event of a communication failure between the two nodes, the winner is chosen by the witness based on the most recently negotiated lock file reported by one or both of the nodes.
A method for dynamically assigning a winning node in an active-active data storage network comprising the steps of:
A system for managing an active-active distributed data processing network, comprising:
A non-transitory computer readable storage medium containing software for dynamically assigning a winning node in an active-active data storage network comprising performing the steps of:
