Balancing when adding a new disk isn't that important unless the two old disks are almost full. > Maybe > sudo btrfs balance start -dusage=100 <mp> Note that this doesn't mean "all data", merely "all data chunks < 100% full". It's a strictly-lesser-than comparison. You'd want "-dusage=101" which is illegal, the right one is "-d". I used to believe -dusage=100 does that, myself.
