From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Bcachefs making progress towards getting included in the kernel. My dream of having a Linux native RAID5 capable filesystem is getting closer to reality.

This is the best summary I could come up with:


While Bcachefs was not merged for the Linux 6.6 cycle with one of the concerns raised by Linus Torvalds being that it hadn't been vetted via the "linux-next" staging area, that process has now begun to raise hopes of potentially seeing the new file-system driver introduced for Linux 6.7.

Overnight the Bcachefs file-system driver was added to the Linux-Next tree as that loose testing area of experimental code that hopes to get into the "next" kernel cycle.

The Bcachefs Git repository is now being pulled into Linux-Next to allow more eyes on the code and all of the automated build/test infrastructure leveraged by various individuals and vendors for testing this leading edge "-next" code.

Having Bcachefs in Linux-Next will lead to much more build testing of the code in different environments and ideally help uncover any lingering bugs before the next Linux kernel merge window opens up in about two months.

So for those interested, Bcachefs is in linux-next.

You tried, bot. You tried.

So excited. The multi tiered storage feature is incredibly useful. Add in some cheap SMR as your lowest tier and you got a very cheap very big pool.

That's definitely an awesome feature. As someone who's spent a small fortune running an all-SSD ZFS RaidZ array, I could have used such a feature two months ago.

I vow from this point forward to always pronounce it, BEE-ka-chefs.

I swear I can only see bca chefs whenever this is posted about.

Ooh, it's supposed to be b cache fs

[–] LeFantome@programming.dev 4 points 1 year ago

I think it is BEE-kash-eff-ess

I much prefer the name of another filesystem, "butterface"

Has somebody a proper comparison with BTRFS and why somebody who is using BTRFS should look into bcachefs?

[–] Turun@feddit.de 2 points 1 year ago (1 children)

Last I checked btrfs raid 5 and 6 support was still not declared as stable.

[–] Molecular0079@lemmy.world 2 points 1 year ago

Neither is the support in bcachefs apparently. Erasure coding which is used for RAID 5 is marked as unstable

[–] RaivoKulli@sopuli.xyz 1 points 1 year ago

I'm wondering the same.
