Warning 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.


To create and manipulate Btrfs volumes, you will need to install

$ sudo apt install btrfs-progs

Debian Jessie

Btrfs being still very young, it is recommended to use recent version of the kernel and btrfs-progs

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


To create a subvolume just use the command

$ sudo btrfs subvolume create /<path>

To create a snapshot use

$ sudo btrfs subvolume snapshot /<source-path> /<destination-path>
