Basically, when your btrfs is full, just create a loopback device, add it to the array, rebalance and then remove the device. This is what I had to do this Sunday :)
I don't know if you saw the beginning of the thread, but what started this whole mess was I allowed a raid6 btrfs filesystem to fill up, and couldn't balance it even after adding a real disk. (I tried a loopback device first.)
Yeah, I already forgot the beginning of the thread :) Although, are you sure that 1 extra disk will be OK? For raid6 you may need to add more than one... HTH, -- Leonid Isaev GPG fingerprints: DA92 034D B4A8 EC51 7EA6 20DF 9291 EE8A 043C B8C4 C0DF 20D0 C075 C3F1 E1BE 775A A7AE F6CB 164B 5A6D
