 Warning: | Btrfs is still a new filesystem. While many (including myself) find it stable enough for everyday use, don't use it for critical services and be prepared to use you backups. See status page on Btrfs wiki for up-to-date info. |
Install
To create and manipulate Btrfs volumes, you will need to install
$ sudo apt install btrfs-progs

Btrfs being still very young, it is recommended to use recent version of the kernel and btrfs-progs
- Kernel from Jessie Backports
$ sudo apt install btrfs-progs/jessie-backports
Create a filesystem
Single Disk
$ sudo mkfs.btrfs /dev/sdb
Raid 1
$ sudo mkfs.btrfs -mraid1 -draid1 /dev/sdb /dev/sdc
Raid 0
$ sudo mkfs.btrfs -mraid1 -draid0 /dev/sdb /dev/sdc
Subvolumes
To create a subvolume just use the command
