I have a raid6 btrfs filesystem which I filled up, and added a disk to:

Despite having removed files, and added the new device, I still can't balance the filesystem:

Did you do it in that order? How about attempting to remove files after adding the new device.
As Guus said, removing a snapshot is more likely to help than removing files.
If you haven't already done so, I'd also suggest posting this to the linux-btrfs mailing list (see https://btrfs.wiki.kernel.org/index.php/Btrfs_mailing_list)
Yes. I've tried removing files after adding the device. Unfortunately, there are no snapshots. I could try removing subvolumes. I'll try the btrfs list. Thanks, Jameson
