There are a whole bunch of pretty serious bugs that have been fixed between then and now. You should really be running a kernel no earlier than 2.6.38: version 2.6.39 is preferable. You should also be using the latest btrfs-progs from the git repository: $ git clone git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-progs-unstable.git $ git co tmp $ make $ sudo make install (You may need the libuuid-devel package to get this to build. There's also a problem with the most recent gcc, but that probably won't apply to you; it's easily dealt with if you do hit it). Once you've made and installed btrfs-progs, you will have mkfs.btrfs, and the btrfs tool, which is used for managing your filesystem. You should also ensure that you're keeping good and regular backups of the data in your filesystem, and be prepared to use them -- btrfs is still considered experimental, and if things go wrong, the fastest way at the moment to get your data back is often to restore from backups.
