将Storm HA Nimbus作为单个实例运行(Running Storm HA Nimbus as a single instance)

 我正在使用Storm 1.0.2。 目前我们有一个小型拓扑，我们只需要运行一个Nimbus实例。 但是，在极少数情况下，我们唯一的Nimbus实例会因磁盘丢失而崩溃，因此创建一个新实例将无法工作。 新实例将转到ZK，由于缺少拓扑数据，将永远不会被选为Leader并且永远不会再次出现。 这是我们面临的问题。 我能想到的唯一工作就是将这些数据存储在一个单独的永久磁盘上，这样即使我们唯一的Nimbus实例发生故障，我们也不会丢失拓扑罐，下一个实例可以成为ZK的Leader，没有任何问题。 
 
 我错过了什么吗？ 有没有其他方法来重置ZK，除了删除nimbus数据（ 以某种方式删除/ storm / nimbus目录不起作用 ）？ 是否有任何配置只能在暂存环境中禁用Nimbus中的领导者选举？ 

I am using Storm 1.0.2. Currently we have a small topology and we only want 1 instance of Nimbus running. However, in the rare event of our only Nimbus instance going down with some disk loss, brining up a new instance will never work. The new instance will go to ZK and because of missing topology data, will never be elected Leader and will never come up again. This is the issue we faced. The only work around I can think of is to store this data on a separate persistent disk so even if our only Nimbus instance goes down we don't lose topology jars and the next instance can be made Leader by ZK without any issues.
 
Am I missing something? Is there any other way to reset the ZK other than by deleting the nimbus data (somehow deleting the /storm/nimbus dir did not work) ? Is there any config to disable leader election in Nimbus for 1 instance only on staging environments?
