我设计了一个docker-compose.yml文件，它应该也可以处理各个卷。

我创建了一个raid驱动器，它作为/dataraid挂载到我的系统中。我可以对系统进行读写，但是在我的撰写文件中使用它时，我会得到read-only file system错误消息。

将卷调整到另一个路径(如/home/myname/test )，复合文件可以工作。

我不知道/dataraid把它变成了“只读”。

撰写文件所需的权限设置是什么？

错误信息：

ERROR: for db  Cannot start service db: error while creating mount source path '/dataraid/nextcloud/mariadb': mkdir /dataraid: read-only file system
