bcachefs

FIRST-HAND READS

What people reported, in their own words. Every line links to where it was said.

• “bcachefs is slowly working up to what you're describing - describing what you want and letting the filesystem sort it out”

  POSITIVE · features · Hacker News · 2026-07-08

• “bcachefs is pushing boundaries there. Making a habit of writing pretty printers for absolutely everything means that now our tracing is the best you'll see in software like this”

  POSITIVE · features · Hacker News · 2026-02-10

• “bcachefs has a high quality embedded database at its core, and one of the dreams has always been to turn that into a real general purpose database”

• “the reason bcachefs's (and bcache's) btree is so fast is that we use much bigger nodes, and we're actually a hybrid compacting data structure. So we get the benefits of LSM-trees (better data structures to avoid binary search for most of a lookup) without the downsides”

• “I love the idea of bcachefs, it gives a lot of the features of btrfs but includes encryption which means no luks song and dance”

• “I'm a happy bcachefs user. Haven't had any issues on a simple mirrored array, which I've been running since before it was in (and out) of the kernel. It's the best filesystem in 2025.”

• “bcachefs has always had one of the better track records at avoiding regressions and quickly handling them when they do get through”

• “BTRFS and BCACHEFS are integral components of the kernel, hence their usage in combination with recompiling LATEST kernels is really a charm”
