看一下租户副本分布。正常情况1-1-1集群是可以提供服务的。

检查一下集群的报警日志，根据报警日志排查问题。

[ob青松]

从截图可以看出有一台主机不可用，导致集群不可用，看看rootservice 在哪一台主机上，估计没有自动迁移到其他主机而导致的！
在截图概览中查看rootservice 是否在宕机的178上面呢！

向大佬学习经验

难道是一台主机挂掉了，剩下的不满足Paxos的多数派么，这个有可能么

这个rootservice是在OCP的库里面查看还是该集群里面呢，如果是该集群里面，都连接不进去了

[AntTech_JN72T2]

178主机里面，没有observer进程
