【 TiDB 使用环境`】生产
【 TiDB 版本】v5.3.0
【遇到的问题】TiDB集群中TiKV是集群3台部署，其中1台误删除/data文件后无法启动
【复现路径】查看了/tidb-deploy/tikv-20160/log
【问题现象及影响】tikv日志报错如下：

按照这篇文档做的（恢复步骤）：
【SOP 系列 18】TiUP 环境恢复 TiKV 副本 - 运维指南 / TiDB 运维手册 - TiDB 的问答社区 (asktug.com)
9. 删除之前的 store id
10. 重启 tikv 集群后正常
运行 第9-10步后，状态变成offline.
缩容使用–force后，使用tiup cluster display tidb ，故障节点已经消失。
使用tiup ctl:v5.3.0 pd -u pdip:2379 store查询，故障tikv节点的store id仍在，执行扩容提示重复的ID
