lfg :marseyletsfuckinggo2: - might finally have an mainline kernel FS that's not as shit as btrfs and without the license incompatibilities of ZFS. :marseywereback:

i only use free software created by killers so it's reiserfs for me

Too bad for you this article links to another about Reiserfs probably getting removed

This filesystem attracted a fair amount of interest in its early days and some distributions adopted it as the default choice, but its own developers quickly moved on to other things

reiserFS buries the competition.

But won't tell you where without a plea deal.

Good. It should have been ZFS but like so much garbage in Linux it's Oracle's fault.

Is it as good as ZFS? Hows the full disk encryption support?

Also: Probably wouldn't trust this like ZFS but as far as I have followed it it does seem to be as robust feature-wise as btrfs with the quality of ZFS.

At the same time I'd encourage you to use it if it is merged so we can make it the gold standard of Linux FSes - I don't think that's happening with btrfs.

I have no clue on native FDE, sorry. It looks like it has full native like ZFS?

Do the docs help:

Bcachefs provides whole-filesystem encryption, using ChaCha20/Poly1305. Encryption may be enabled when creating a filesystem, or encryption may be enabled on an existing filesystem (TODO: implement interface for enabling encryption on an existing filesystem - kernel code exists).

Hopeful for this. Would be super nice to have a zfs equivalent or better in the mainline kernel.

for real. Finally a true answer to "what modern FS should I use"

>Scalable - has been tested to 50+ TB, will eventually scale far higher
>Already working and stable, with a small community of users

Am I the only one who thinks most of this shit doesn't belong on a filesystem? Read/write the data as fast as possible, and make sure it stays there until it's deleted. That's essentially all a filesystem should do.

Compression doesn't belong on a filesystem. Not everything needs compressing and makes simple stuff like checking remaining space difficult.

Encryption you do via LUKS and doesn't need to be a filesystem thing.

CoW and snapshots should not be filesystem level and fricks around further with remaining disk space.

Multiple devices you can either use mdadm or LVM. Why reinvent it and put it on the filesystem?

etc etc

surely a lot of that stuff can be more efficient reliable etc if its hidden from the user in the autism part of the operating system

if youre a homelab cuck or whatever then fine but who wants to manually set up CoW in userspace? how would that even work

I don’t think I need to argue for it explicitly when zfs is the best example possible.

Nilfs is peak filesystem, simple fast , no feature bloat

Please, btrfs is absolute trash and I hate all the modern distros that are starting to make it the default.
