Meet Linux's Newest File-System: Bcachefs

An anonymous reader writes: Bcachefs is a new open-source file-system derived from the bcache Linux kernel block layer cache. Bcachefs was announced by Kent Overstreet, the lead Bcache author. Bcachefs hopes to provide performance like XFS/EXT4 while having features similar to Btrfs and ZFS. The bachefs on-disk format hasn't yet been finalized and the code isn't yet ready for the Linux kernel. That said, initial performance results are okay and "It probably won't eat your data — but no promises." Features so far for Bcachefs are support for multiple devices, built-in caching/tiering, CRC32C checksumming, and Zlib transparent compression. Support for snapshots is to be worked on.

Why? What advantages does this have over ZFS?

Instead of yet another FS flavor of the month, or year, (Reiserfs, Btrfs, Bcachefs, etc.) and all the man-hours wasted re-solving the same old problems how about just doing it right the first time (ZFS) ?? Because this is what it is turning into. What advantages bachefs have over ZFS??? There is no way in hell I'm going to trust an unproven, buggy, and incomplete FS when we already have one that works.

Fixing the Butr free space shenanigans would have been a step in the right direction: An existing debugged FS.

Reminds me of this xkcd #927: Standards

Hmmmm

I guess writing a new filesystem is easier than fixing the existing bugs in bcache itself.
