I'm not a quota/qgroup user either, but FWIW, after someone else reported problems (in that case, performance related) that I suspected were quota related, as they ultimately turned out to be, he did say that simply disabling quotas wasn't enough, he had to delete the quota tracking metadata to eliminate the issue. Without personal btrfs quota feature experience I can't supply details as to what that involves, but he did specifically mention that simply disabling them didn't solve the problem, while removing them did. -- Duncan - List replies preferred.
