> 如果 server2 已经初始化过，现在只是重启恢复 region1，那么它的 conf 会从 pd server 上获取，这个如果要修复的话可能需要在 split 成功后往 pd server 写一下 server2 的 conf 数据（由发起 split 的 leader 执行）？这样在 server2 启动是就会启动 region 1000000 @fengjiachun Hi，请问下这里重启节点从pd server拉取最新的配置（只有pd有最新分裂后region信息）传递给启动节点的操作，这里要业务层自己来实现么（在启动时业务自己调用pd...

@fengjiachun 这里只是在阅读代码发现的疑问 此处强制校验必须相等 `rOptsList.size() == regionList.size()` https://github.com/sofastack/sofa-jraft/blob/0a79d749791e28f58b83262e7287a0cd4c4f3b21/jraft-rheakv/rheakv-core/src/main/java/com/alipay/sofa/jraft/rhea/StoreEngine.java#L671 其中`rOptsList`来自本地配置文件 https://github.com/sofastack/sofa-jraft/blob/0a79d749791e28f58b83262e7287a0cd4c4f3b21/jraft-rheakv/rheakv-core/src/main/java/com/alipay/sofa/jraft/rhea/StoreEngine.java#L669 `regionList`来自`store`，`store`从pd获取 https://github.com/sofastack/sofa-jraft/blob/0a79d749791e28f58b83262e7287a0cd4c4f3b21/jraft-rheakv/rheakv-core/src/main/java/com/alipay/sofa/jraft/rhea/StoreEngine.java#L670 https://github.com/sofastack/sofa-jraft/blob/0a79d749791e28f58b83262e7287a0cd4c4f3b21/jraft-rheakv/rheakv-core/src/main/java/com/alipay/sofa/jraft/rhea/StoreEngine.java#L177 如果本地配置最初写的2个region，运行中被pd分裂为3个region之后，节点宕机重启时似乎671行校验永远通不过？ `rOptsList.size 2 != regionList.size 3` ？
@fengjiachun 我来重新简单描述下问题，在走读代码过程发现的疑问：当PD主动触发分裂后，PD中获取最新region数量比本地配置的regionEngineOptionsList要多，那此时如果该节点宕机重启，此处校验似乎无法通过？ 
好的，后续我单提一个issue和pr，这里有思路和建议么？应该不需要将整个本地regionEngineOptionsList都放到pd中吧
