Embodiments of the present invention disclose an arbitration processing method after cluster brain split, an arbitration processing apparatus, and a system. The method includes: receiving, within a detection period, master quorum node preemption requests sent by quorum nodes in a cluster, where each master quorum node preemption request includes an identifier of a quorum node; determining, according to a pre-recorded identifier of a master quorum node, whether the received master quorum node preemption requests include a master quorum node preemption request sent by the master quorum node; when the received master quorum node preemption requests include the master quorum node preemption request sent by the master quorum node, maintaining the pre-recorded identifier of the master quorum node; when the received master quorum node preemption requests do not include the master quorum node preemption request sent by the master quorum node, changing, after the detection period, the pre-recorded identifier of the master quorum node to an identifier of a quorum node corresponding to a master quorum node preemption request that arrives at a quorum storage apparatus first; and sending a master quorum node preemption success response message to the quorum node corresponding to the recorded identifier, where the response message is used to notify the quorum node corresponding to the recorded identifier that master quorum node preemption succeeds. |
