Bcachefs Goes to "Externally Maintained"

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.

There's literally ZFS-on-linux and it works great. And yes, I will once again say Linus is completely wrong about ZFS and the multiple times he's spoken about it, it's abundantly clear he's never used it or bothered to spend any time researching its features and functionality.

ZFS deserves an absolutely legendary amount of respect for showing us all what a modern filesystem should be - the papers they wrote, alone, did the entire filesystem world such a massive service by demonstrating the possibilities of full data integrity and why we want it, and then they showed it could be done.

But there's a ton of room for improvement beyond what ZFS did. ZFS was a very conservative design in a lot of ways (rightly so! so many ambitious projects die because of second system syndrome); notably, it's block based and doesn't do extents - extents and snapshots are a painfully difficult combination.

Took me years to figure that one out.

My hope for bcachefs has always been to be a real successor to ZFS, with better and more flexible management, better performance, and even better robustness and reliability.

Long road, but the work continues.

Say more? I can't say I've really thought that much about filesystems and I'm curious in what direction you think they could be taken if time and budget weren't an issue.
