      lol, that's still a thing? I was hitting the same problems 3 years ago and that already put me off btrfs forever. It's fine I guess nobody needs their FS to be writable anyway.https://twitter.com/septajohn/status/1265192454480777217 …

      idk, my system partition was too small for regular system updates on ubuntu 18.04, so I always forgot to remove one kernel version before upgrading, and always ran out of space. Deleting and retrying always worked fine. Haven’t had any real issue with btrfs since 2017 or so.

      My mom on the other hand always managed to do something weird every few months during 16.04 cycle, but she’s back on windows for various unrelated reasons, so I lost some valuable data point

      This is not an "out of free bytes" issue. This is btrfs insanity with its automatically managed "metadata space" running out, and it not being able to recover from this.

          See for example https://btrfs.wiki.kernel.org/index.php/FAQ#Help.21_Btrfs_claims_I.27m_out_of_space.2C_but_it_looks_like_I_should_have_lots_left.21 … or https://btrfs.wiki.kernel.org/index.php/FAQ#or_My_filesystem_is_full.2C_and_I.27ve_put_almost_nothing_into_it.21 … "So, in general, it is impossible to give an accurate estimate of the amount of free space on any btrfs filesystem. Yes, this sucks." I agree.

          Yes, I have encountered this issue before, a long time ago. What I’m saying is that I’ve been using 18.04 for a couple of years on a very space constrained partition and haven’t had a single problem specific to btrfs.

          idk how suitable it is for real world usage in enterprise, but there’s been a lot of effort put into it to meke it more resilient and stable for everyday casual usage at least
