数据盘丢失恢复后强制缩容无法删除已缩容节点
【TIDB使用环境】
线上环境
【概述】概述+问题描述
1.172.168.1.224:/data2与172.168.1.227:/data2两块磁盘故障,/data2分区消失导致172.168.1.224:20172与172.168.1.227:20172节点丢失
2.重启服务器并重新挂载找回消失的/data2,但节点启动失败,错误信息未保留;
3.手动缩容节点(使用了–force)
tiup cluster scale-in clustername -N 172.168.1.224:20172
tiup cluster scale-in clustername -N 172.168.1.227:20172
4.重新增加节点
扩容配置文件:cat scale-out.yml

扩容完成,但是启动节点失败报如下错误:

执行手动删除命令提示成功但是实际上并未删除

【背景】做过哪些操作
【现象】业务和数据库现象
发生故障后数据库整体读写异常,重启整个集群后,读取正常写入严重超时4min以上
【业务影响】
业务无法正常写入
【TiDB 版本】
6.1.0
