It's orphaned in Debian as well, but I'm not sure what significant advantages it has over btrfs, which is very stable these days.

btrfs was unusable in multi disk setup for kernels 6.1 and older. Didn't try since then. How's stable btrs today in such setups?

The sad part, that despite the years of the development BTRS never reached the parity with ZFS. And yesterday's news "Josef Bacik who is a long-time Btrfs developer and active co-maintainer alongside David Sterba is leaving Meta. Additionally, he's also stepping back from Linux kernel development as his primary job." see https://www.phoronix.com/news/Josef-Bacik-Leaves-Meta

There is no 'modern' ZFS-like fs in Linux nowadays.

It's sort of frustrating that this constantly comes up. It's true that btrfs does have issues with RAID-5 and RAID-6 configurations, but this is frequently used (not necessarily by you) as some kind of gotcha as to why you shouldn't use it at all. That's insane. I promise that disk spanning issues won't affect your use of it on your tiny ThinkPad SSD.

It's important to note that striping and mirroring works just fine. It's only the 5/6 modes that are unstable: https://btrfs.readthedocs.io/en/stable/Status.html#block-gro...

Damn. I was enjoying not having to deal with the fun of ZFS and DKMS, but it seems like now bcachefs will be in the same boat, either dealing with DKMS and occasional breakage or sticking with the kernel version that slowly gets more and more out of date.

Your distro could very easily include bcachefs if it wishes? Although I think the ZFS + Linux situation is mostly Linux religiosity gone wild, that very particular problem doesn't exist re: bcachefs?

The problem with bcachefs is the problem with btrfs. It mostly still doesn't work to solve the problems ZFS already solves.

Ad hominem. My thinkpad ssd is massive.

Respectfully to the maintainers:

How can this be a stable filesystem if parity is unstable and risks data loss?

How has this been allowed to happen?

It just seems so profoundly unserious to me.

But RAID-6 is the closest approximation to raid-z2 from ZFS! And raid-z2 is stable for a decade+. Indeed btrfs works just fine on my laptop. My point is that Linux lacks ZFS-like fs for large multi disc setups.

FWIW DKMS is not the only way to distribute out of tree modules.
