昨天按原配置搭了一套新的集群，启动正常，然后把旧集群pd、kv的数据文件复制到新集群下进行启动，发现这个方法行不通，同时旧集群也被新集群污染了，启动的时候发现新集群有到旧集群的连接，怀疑pd的数据文件里面记录了集群信息，此时关掉了新集群，发现旧集群有一个pd Down了，启动报错：
[2023/12/13 20:44:55.410 +08:00] [ERROR] [kv.go:295] [“fail to load safepoint from pd”] [error=“context deadline exceeded”]
[2023/12/13 20:44:55.528 +08:00] [ERROR] [pd_service_discovery.go:221] [“[pd] failed to update member”] [urls=“[http://172.16.26.212:2379,http://172.16.26.213:2379,http://172.16.27.211:2379]”] [error=“[PD:client:ErrClientGetMember]get member failed”]
还能抢救吗？
