tiup安装tiflash节点报错

[tao7]

tidb版本：v4.0.1
安装过程：在现有tidb集群安装一个tiflash节点，最后阶段报错如下
问题：遇到这个报错后续如何处理？我使用tiup cluster display test-cluster观察，实际上tiflash已经起起来了，但我从监控里看不到tiflash相关的信息，通过ps查看该节点上也只起了tiflash这个进程，相关监控没有起

你好，

请提供以下信息，以便排查问题

1. 请提供下 edit-config 看下原集群 topo，并附赠 display 截图
2. scale-out 的 topo 文件烦请也上传下
3. 看下 tiflash/log 下的所有 log 文件请打包上传下。这边看下是否有更详细的报错

[tao7]

这个问题结贴。我通过重做tiflash节点，运行扩容命令时增加–wait-timeout 300参数，问题解决

你好，

通过 scale-in ，scale-oout 解决了？

[tao7]

是的，先scale-in缩容，清理节点上的安装信息，再scale-out，scale-out的时候因为tiflash启动慢，把wait-timeout由默认的60s改成300s
