> 1. 启动3副本 , 3C5D集群
> 2.调用stop-datanode.sh脚本正常停止ip76的 datanode 
> 3. benchmark写入数据完成
> 4. 缩容下线的ip76的datanode
> confignode 会重试连接ip76 ，并且有DELETE_OLD_REGION_PEER重试操作，DELETE_OLD_REGION_PEER可以不执行，因为不是缩容开始后的重试 :
> 2022-11-02 14:34:23,637 [ProcExecWorker-9] ERROR o.a.i.c.c.s.SyncDataNodeClientPool:113 - {color:#DE350B}*DELETE_OLD_REGION_PEER*{color} failed on DataNode TEndPoint(ip:192.168.10.76, port:9003) 
> 5. 启动 ip76 datanode ， 可以看到remove开始在 ip76上执行 ，但此时此节点的状态却是Running, 应该是Removing。
> ip76 datanode log （已经在执行remove了）：
> 2022-11-02 14:38:45,611 [pool-53-IoTDB-Region-Migrate-Pool-1] INFO  o.a.i.d.s.RegionMigrateService$DeleteOldRegionPeerTask:493 - succeed to remove region DataRegion[12] consensus group
> 此时集群节点状态：
