常见错误解决 ​

最开始安装过一次，以为tiflash必须要配置两个才能来起来，所以想尝试重新部署一次

但是正常 tiup clean --all 删除所有组件之后，修改topology.yaml的tiflash配置重新部署，出现如下报错

解决方案为，进入/home/tidb/.tiup/storage/cluster/clusters目录下删除tidb-test的文件

本人猜测可能是clean的时候没有将这部分文件一起删除导致的

shell
[tidb@tiup-tidb41 ~]$ export TIUP_MIRRORS=/home/tidb/tidb-community-server-v4.0.2-linux-amd64

[tidb@tiup-tidb41 ~]$ tiup cluster deploy tidb-test v4.0.2 topology.yaml --user root -p
