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.
# 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).
