/etc/fstab里每一项都添加了节点 还是不行
不是要每一项都加，需要满足 tidb 装载要求的才加，而且每个环境都不一样，只能依靠你自己排查 
正常情况是不需要用 / 根目录的。都是装在挂载的文件系统下面的，你把 yaml 配置文件完善一下吧。把 data_dir 和 deploy_dir 都设置一下，不要使用 / 根目录。
您的意思是只需要data_dir 和 deploy_dir所在的盘挂载吗
是的，你不是三块盘，挂载了三个文件系统/data1, /data2, /data。
你把安装目录还有数据目录都放在你挂载的盘上。对这些盘设置 nodelalloc 和noatime 参数就行了。不要去动根目录。
你的yaml文件指定一下data_dir 和 deploy_dir，tiup 应该就不会去检查 / 了。
apply以后，显示如下，启动集群还是显示check bootstrapped failed

是我系统的问题吗？但是文档显示6.1.0是支持ubuntu16.04以上的啊
和系统应该没关系，还是你磁盘配置有问题，这是我的配置，你参考一下，按照你的环境修改
