    I think the reviews should also include the social aspect of these filesystems...

    There is and have been many promising and exciting FS to replace the old boring ones, but for storage you not only want to avoid technical issues but also maintainer(s) drama...

      Why do people keep bringing up drama?

      The community infighting has sucked, but that's a thing that matters primarily for maintainers.

      I think most users just want something that works.

        To answer the original question, most people who care about their filesystem at all care about its stability. Not just "does it work now" but also "will it work and improve over time". Infighting puts the future at risk.

          It really does.

          But you might want to check out the bus factor on btrfs too; when a maintainer says "but we've saved Facebook billions and billions of dollars!", calls for the other filesystem maintainer to be ejected from the community, then quits to join Anthropic a month later - that's not a vote of confidence.

          I'd be very happy if people could just stop bringing up drama and us factors. We put it behind us a year ago, but it seems not everyone got the memo.

            Checking the bus factor:

            Btrfs regulars:

            - 1 from Meta

            - 1 from Oracle

            - 4 from SuSe

            - 2 from WDC

              Might end in a new bcachefs fork beeing included back into mainline. If companies sponsor a few fulltime devs working on the new fork, we finally might have a stable enterprise ready CoW filesystem.

                Uhh, do you know what the upstream stance is on testing and fixing bugs?

                I doubt there'd be any real interest in a bastardized fork that only exists so the deep pocketed vendors can get away with code dump and run.

                  Thought about a real fork going in its own direction. I would love to use bcachefs in all our products. But the current state does not qualify for usage within enterprise environments. Any ideas how to get that fixed? How many core developers are present? Any fallback plans, ...? How to help to get there?
