In this chapter, we will investigate what is on offer with btrfs (pronounced as Better FS). Although not directly related to networking, we will soon look at how to share filesystems; for this reason and as btrfs is so incredibly good, we will take a look at it right here and right now. Btrfs is a local filesystem that provides the benefits of integrated volume management operations with easy growth and a fault-tolerance built-in the filesystem. It's not fully supported by Red Hat and ships as a technology preview; it has to be said that Red Hat is cautious on this matter because SUSE has had btrfs as their default filesystem since Enterprise Linux 11 SP2 and continues on SLES 12.
