Here’s the thing. Bcachefs is still under development, and Kent is really careful with his filesystem. This happens to me every now and then if I havent rebooted in a long time or theres a kernel update with filesystem changes it doesn’t like. The trick is to skip the userspace fsck code and pass the -k flag so it uses the kernel fsck code which is much farther along. I’ve never lost anything on this filesystem and its messed up in lots of bizzare ways.
ext4 doesnt do tiered storage. I could make an LVM and have it pool things into one storage volume but I wanted to learn this. bcachefs is simpler and cleaner, but it’s still young and very volatile. Also, ext4 does have bugs still, even today.

but why not just use ext4, which isnt buggy?
