Google Admin Encourages Trying Btrfs, Not ZFS On Linux.

Marc Merlin's presentation at Linux.Conf.Au 2015 was entitled "Why you should consider using Btrfs, real COW snapshots, and file level incremental OS upgrades." The talk was much like the one last August at LinuxCon Chicago where he was trumpeting Btrfs. Aside from openSUSE beginning to ship with Btrfs by default, most Linux distributions still tend to be EXT4/XFS based and leaving Btrfs as just an experimental install-time option. In fact, CoreOS switched away from Btrfs to EXT4+OverlayFS. Whether or not this next-generation Linux file-system is ready for production use remains a very controversial topic.
