Provided in an embodiment of the present invention are a cluster arbitration method and multi-cluster coordination system, the method in the embodiment of the present invention comprising: detecting whether failure occurs in a first cluster set or a second cluster set, and the first cluster set comprises a portion of a first cluster, a portion of a second cluster, and the second cluster set comprises another portion of the first cluster and another portion of the second cluster, and the first cluster and the second cluster coordinate with each other; when a failure is detected, the first cluster set and the second cluster set each determining a preemption representative respectively, the preemption representative of the first cluster set and the preemption representative of the second cluster set respectively executing the following steps: determining whether the failure occurs inside said cluster set; if not, preempting an arbitration device, and the cluster set having the preemption representative successfully preempting the arbitration device according to a preset arbitration mechanism survives. The present invention can reduce the probability of service access interruption. |
