Clust_mgr is an important compnent of KunlunBase. It provides a HTTP API for KunlunBase users to do cluster management, provisioning and monitor work, so that uses can install a cluster, a kunlun-server node, a storage shard or a kunlun-storage node by calling such APIs. Such capability enables users to integrate KunlunBase management and provisioning as part of their existing application or GUIs. Cluster_mgr also provide other important cluster maintenance background work to make sure the KunlunBase clusters it serves can work efficiently and reliably.

该功能与新增一个storage node不同，专用于备机无效（主备研吃过大或者备机复制卡住）的情况。

  1. 使用主节点在收到命令的时候做备份，不要使用集群整体的备份数据。这样可以避免追binlog的时耗
  2. 新的备机节点放到原备机节点所在的机器上面去以便遵循peer部署架构。
  3. 可以一次选择一个或者多个或者一个storage shard的所有备机节点同时做备份
  4. 把备份数据从主节点复制到每个需要重做的备机节点所在的机器，用完后删除
  5. 为新做好的备机节点建立主备关系，然后停掉老备机节点的主备复制
  6. 增加了新备机节点到shard后，把原备机节点disable掉，但是不要删掉，让DBA删除
