Weird. There should be a bunch of messages in dmesg during a normal/successful balance, and either something mentioned or missing might provide a clue why some chunks weren't converted. Unmounted, what do you get for btrfs check? > > Do you have an idea what could be wrong? No. I'd say it's a bug. 3.14rc3 should be out today, and might be worth a shot. Or btrfs-next. If you try again, you only need to convert the data profile. Also, 10 hours to balance two disks at 2.3TB seems like a long time. I'm not sure if that's expected.
