那个，大神有个尴尬的问题：我春节7天没有动这个，现在打开一下，还是这个状态：Pending offline：
日志报错：
1、可以使用 -froce 强制下线，但下线后，需要确认 pd-ctl store 看看还有没有该节点，如果有使用 需要使用 prune 命令，删除 tombstone 状态的节点
2、去下线的服务器上，查看原先的进程端口是否还存在，正常是不存在的，确认不存在后，再扩容
好的，我试试，先谢谢了
ok
- 确认一下目前 tiup cluster display 的状态
- 确认一下目前集群有没有 down 的 region 。可以通过 pd-ctl 来查看。
https://docs.pingcap.com/zh/tidb/stable/pd-control#region-check-miss-peer--extra-peer--down-peer--pending-peer--offline-peer--empty-region--hist-size--hist-keys - 再使用 pd-ctl 给一下所有的 store 信息。看看是不是之前缩容的时候的 store 没下掉。
1、tiup cluster display的状态;
2、执行 region check miss-peer指令后有返回值，应该是有down的region

我是要把所有为down的region都删掉嘛？额，这个没弄过。。。。。
