【 TiDB 使用环境】测试
【 TiDB 版本】

会不会是磁盘问题导致的呢？

把所有的操作步骤也发下？以及tidb的集群版本也发下？

@月明星稀

slow disk

磁盘太慢？参照官方文档，做个fio测速看看呢

[tidb菜鸟一只 (小菜一颗)]

什么环境啊，拓扑发一下，原集群是通过 tiup cluster destroy销毁的不？
主要看下pd的日志，如果pd没起来其他起不来的

[小龙虾爱大龙虾 (Minghao Ren)]

空集群的话，再重新销毁重建下，销毁的时候保证目录都清空了

[tidb狂热爱好者]

空目录吗？

[cchouqiang]

把所有的目录都删除，还有/etc/systemd/system下面的tidb相关的service文件删除；
在重新创建集群。
