关于TIDB4.0版本日志报错的问题

在上面提示的错误经查不是因为SSH互信免登录原因，而是
monitoring_servers:

• host: 192.168.22.143

grafana_servers:

• host: 192.168.22.143

alertmanager_servers:

• host: 192.168.22.143
  配置需要放在EXT4格式的数据盘上。后来我在虚拟机上挂载了EXT4就没有问题了，安装布署通过

问下，是 windows 的盘吗？

[来了老弟]

hi，请问下问题是否已经排除了呢

[bcd128]

TIDB环境已经全部解决，主要是EXT4格式引起的。

[来了老弟]

是在什么位置发现了有用的信息，定位到 ext4 的问题的吗

[bcd128]

是安装过多次之后，一直是报SSH免密错误，但是又不是这个问题引起的，后来查看官网配置SSD是数据盘是需要格式化成EXT4才能一键使用Tiup

您好，这个报错看起来应该和 ext4没有关系，您可以试试xfs的盘应该也可以安装成功。感觉上面的问题是由于更换了盘重新指定了用户和属主权限，可能解决了问题，多谢。

好的，我试一下。
