Oh, so bcachefs is doing pretty well.

  Except for the fact that the developer has sabotaged the project into being removed from mainline?

    That might be the best thing happened to the project since now development can happen at its own pace without the clicky bait influencers.
    In fact they delivered the erasure coding for parity raid back in march this year.
    The thing is that as soon as you seriously give a chance to Bcachefs you see how good it is. I can only tell you that mixing different device tiers and having a per-file/directory replication setting is a god send specially in these times where storage costs more than gold.

    I'm pretty sure Bcachefs is amazing and better than Btrfs. I also think Zfs is amazing and better than Btrfs. Even so, I still use Btrfs because I know it is guaranteed to always be present on any Linux without any effort on my part.

    A better approach might have been to just paused mainline merging instead of forcing being kicked out?
    Eg "Hey Linus, Bcachefs is still in early development and I need to merge changes in a pace that is not compatible with Linux development process. So I'm going to pause for a while now and once it reaches maintenance status I will focus on submitting patches in a healthy pace that you can digest".

    100%. My system is rock solid and the last thing I need is rolling the dice after every update on whether my system will boot. <a href="https://www.reddit.com/r/archlinux/comments/eywcp7/linux_551_broke_zfs_cannot_boot/" rel="nofollow">https://www.reddit.com/r/archlinux/comments/eywcp7/linux_551...
    I'm impressed with bcachefs's accomplishments though, and if they ever reconcile with the kernel I'll surely give it a fair shake.

    btrfs has one critical issue they don't fix: it blocks access to fs for minutes if you remove large files. I am not sure how this is acceptable for prod grade fs..

    Only if you have quotas enabled IIRC.
