Hi Jeff! Thanks for the enlightening e-mail. It was clear that the qgroups were not the root cause of my issue as you said. I can confirm that even without this feature, the bug still happens in the same frequency. I am glad to know a little bit more how things work with SLE and, now, with Leap. Unfortunately, I will also not be able to change my distro from TW to Leap because I need kernel 4.6 at least. But I do have a side question: I understood that SLE and Leap do not seem to have any major problems with qgroups, but, since Tumbleweed use almost a vanilla kernel w.r.t. BTRFS, should it can also be considered stable there? Back to my bug, one thing that **always** happens is that after the discussed problem, the metadata increases **a lot** (I saw something like 80 GiB once). Hence, is there any kind of configuration to fix the minimum metadata size? If it is, do you think that I can get rid of those ENOSPC by fixing a very high limit, such as 300 GiB? Ah! I think I forgot to mention one very important thing: I have been using Tumbleweed+BTRFS on this machine for a very very very long time. I think I installed it just after it changed to the current model. By that time, I was using the same machine but without one peripheral that requires a "new" kernel (HDD, processor, RAM, everything was the same). AFAIK, the first time I saw that problem was this year. So, I think it must be a regression after some kernel / btrfs-progs update.
