一种利用可迁移虚拟共识节点在双节点集群中维持共识集群多数派的方法、系统、终端及存储介质
By deploying virtual consensus nodes in a two-node cluster and migrating or restarting them in case of failure, the problems of insufficient majority commit and state continuity in a two-physical-node system are solved, thus achieving the stability and availability of the consensus cluster.

AI Technical Summary
In a dual-physical-node system, it is difficult to maintain the majority commit condition. Traditional witness schemes cannot support the consensus protocol state and have insufficient state continuity after failover.
In a dual-node cluster, first and second consensus nodes are deployed, and virtual consensus nodes are created. Their persistent state is saved to shared storage. The high availability management module determines the running host. When a fault is detected, the virtual consensus node is migrated or restarted on the surviving node to form a logical three-member consensus cluster that satisfies the majority submission condition.
It achieves the continuity of majority commit capability in the consensus cluster without adding a third physical node, reduces the risk of split-brain, and improves the availability of the control plane of dual-control devices.
