Hopefully it's obvious I mean run journalctl -f on the affected computer remotely via ssh.

Do you think that if I reinstall my openSUSE it will be fixed?Probably but the nature of this probem isn't well understood as far as I know. It's not that common or it'd be easy for a dev to reproduce and then figure out what's going on.
Since this file system has relatively small metadata size, just under 2GiB, it might be useful to take a btrfs-image of it and put it up somewhere like a google drive, or wherever it can remain for a while. Options -t 4 -c9 -s are fairly standard and sanitize file names. Data itself is not included in the image. From this I think a dev might be able to figure out what's unique about this file system that results in the bogus enospc. If you do this, I recommend filing a bugzilla.kernel.org bug and include URL to the image and URL to this thread, and then the bugzilla URL in a post on this thread that way everything is cross referenced. -- Chris Murphy
