如何删除offline状态tikv

🪐 TiDB 技术问题
1

【 TiDB 使用环境】生产环境
【 TiDB 版本】 v5.3.1 3副本
【复现路径】做过哪些操作出现的问题
误操作强制缩容了1个kv节点， tiup scale-in tidb -N 172.16.61.21:20160 --force -y
然后又扩容了1个kv节点， 目前集群状态正常
【遇到的问题：问题现象及影响】
用tiup看集群信息已经无缩容节点， 用pd-ctl stores 获取缩容节点信息 状态是offline，region count 120 。

缩容后数据目录已经不存在，用什么方法删除这个节点

PD-CTL 终端中执行 remove <store_id>

pd v5.3.1 没有这个命令 pd-ctl store delete <store_id>只能把tikv变成offline状态

pd-ctl [command]

用remove

送你一个小工具，先把store上的region都清理掉，再执行store remove-tombstone
