This is just a rave-post to praise Duncan for his excellent post back to
Jon!
This will surely help a good number of new btrfs users who have the good
sense to watch this mailing list. Your exposition on the balance command
helped to clarify in my mind exactly why someone might want to use the
usage= filter with a given figure (it looked like black magic to me
before, and its usefulness still wasn't completely clear to me after
reading the wiki). You had a lot of practical advice for making and
maintaining a new btrfs filesystem. I run a btrfs as my root as well,
created under kernel 3.2 and purring right along while I've since moved
the kernel to 3.9. I recently updated the userspace tools to 3.12 (from
the distro-provided 0.19+something), so I'll be sure to move the kernel
up to 3.12 as well before trying anything complex.
Thanks for the effort.

Meanwhile, I strongly urge you to read up on the btrfs wiki. The
following is easy to remember and bookmark:
https://btrfs.wiki.kernel.org
Here's the documentation link (alternate bookmarking candidate):
https://btrfs.wiki.kernel.org/index.php/Main_Page#Documentation
Here's the discussion that would have gotten you out of this specific
bind (long link, watch the wrap):
https://btrfs.wiki.kernel.org/index.php/
FAQ#if_your_device_is_large_.28.3E16GiB.29
And here's the balance-filters page, which can be a bit hard to find altho
it's linked on the FAQ page under the balance discussion:
