It may not please you - I've seen this nasty effect too. Reproducable. I presume that "balance" eats disk space. But "balance" seems to be necessary if I want to delete a device, and deleting a device is one of the features I'd like to use with btrfs (adding a new bigger device, then deleting an old smaller device). Viele Gruesse!
