Quick start 快速开始 

For a really quick start you can simply create and mount the filesystem. Make sure that the block device you’d like to use is suitable so you don’t overwrite existing data.
对于真正快速的开始,您可以简单地创建并挂载文件系统。确保您想要使用的块设备适合,以免覆盖现有数据。

# mkfs.btrfs /dev/sdx
# mount /dev/sdx /mnt/test

The default options should be acceptable for most users and sometimes can be changed later. The example above is for a single device filesystem, creating a single profile for data (no redundant copies of the blocks), and DUP for metadata (each block is duplicated).
默认选项对大多数用户来说应该是可以接受的,有时可以稍后更改。上面的示例是为单个设备文件系统创建一个数据的单个配置文件(块没有冗余副本),以及为元数据使用 DUP(每个块都有副本)。
