Can I try to fix it somehow? Running btrfs check --repair /dev/xvda2 doesn't solve the problem. As I wrote, when I then boot regularly the / partion is out of space.
Hi
Check down in /var/log for big files, check those for clues (maybe even copy them off to an external drive), especially messages log.

Maybe it's coredumping?

Run;

Code:
coredumpctl list
If there are old logs you think can be deleted, remove those and see how it goes getting some disk space.
