GitHub user drivebyer added a comment to the discussion: 部署 3 节点 controller
，broker 状态 alive 显示为 false
感谢回复。
刚才我又使用同样的步骤测试了一下，出现了不同的现象。
### controller
```
[root@master0 ~]# kubectl -n mcamel-system exec -it controller-1 -- ./mqadmin
getSyncStateSet -a 127.0.0.1:9878 -c broker -b broker-0
#brokerName broker-0
#MasterBrokerId null
#MasterAddr null
#MasterEpoch 2
#SyncStateSetEpoch 1
#SyncStateSetNums 1
InSyncReplica: ReplicaIdentity{brokerName='broker-0', brokerId=1,
brokerAddress='192.168.137.114:10911', alive=false}
NotInSyncReplica: ReplicaIdentity{brokerName='broker-0', brokerId=2,
brokerAddress='192.168.84.226:10911', alive=true}
```
nameserver:
```
[root@master0 ~]# kubectl -n mcamel-system exec -it name-service-0 -- ./mqadmin
clusterList -n 127.0.0.1:9876
#Cluster Name #Broker Name #BID #Addr
#Version #InTPS(LOAD) #OutTPS(LOAD) #Timer(Progress)
