I think, I somewhat destroyed my btrfs filesystem on my Ubuntu 13.04 kernel

What's the easiest way to determine the size of snapshots/subvolumes?
As I come from a Solaris/FreeBSD background with ZFS, I compare the

Hi
FWIW, I've also written a script which creates and "manages"
(ie. deletes old) snapshots.
It figures out all the available filesystems and creates snaps
for all the available (sub)volumes.
It's also on https://copy.com/WI9AXqTH2nD4 and http://pastebin.com/YX8WKcsR
to avoid line break issues

Fair point :)
I don't plan to boot from the disk, though. It's a data disk, if you will.
But, yeah, for a "best practice", that's certainly something to keep in mind.

If I want to manage a complete disk with btrfs, what's the "Best Practice"?
Would it be best to create the btrfs filesystem on "/dev/sdb", or would it be

/dev/sdb1"?
Would the same recomendation hold true, if w

On my HP Compaq dc5800 with Ubuntu 13.04 and their 3.8.0-19-lowlatency

them below or at http://pastebin.com/bLXPBX67 (to avoid line breaks…).
These kernel traces all begin with:
