GitHub user lixiang365 edited a discussion: 5.3版本
controller模式，两个broker,有一个是不同步副本
版本5.3.0
docker 部署
三个namesrv, 每个都打开了controller
两个broker, 都打开了proxy
```
#brokerName broker-a
#MasterBrokerId 1
#MasterAddr 10.99.155.247:10911
#MasterEpoch 5
#SyncStateSetEpoch 2
#SyncStateSetNums 1
InSyncReplica: ReplicaIdentity{brokerName='broker-a', brokerId=1,
brokerAddress='10.99.155.247:10911', alive=true}
NotInSyncReplica: ReplicaIdentity{brokerName='broker-a', brokerId=2,
brokerAddress='10.99.155.248:11911', alive=true}
```
部署完就是这样。
日志没有报错
这个问题该如何解决？目前不会自动切换
补充broker1 日志

关闭broker1, broker2日志 就会出现无法选举主节点
