版本：--03134283938-20221019-172201-20018

测试1

系统没有启动确认监视器

关闭节点3网卡

登录节点1检查主库状态

显示向节点2发送归档成功，但无法收到节点3的消息，节点1挂起

日志报错如下：

但检查主库状态依旧是suspend

重启（SHUTDOWN后被watcher自动拉起）数据库后再检查状态恢复正常

测试2

启动节点2上的确认监视器

中断节点3的网络

登录主库检查状态

虽然到TEST3发送归档失败，但主库状态正常

主库日志信息如下：

日志显示主库被挂起后立刻状态恢复为open

测试3

启动节点2上的确认监视器

中断节点2的网络

登录主库检查状态

网络恢复后节点2也变成了主，集群分裂

登录监视器显示如下：

集群分裂后只能重建
