It's sort of frustrating that this constantly comes up. It's true that btrfs does have issues with RAID-5 and RAID-6 configurations, but this is frequently used (not necessarily by you) as some kind of gotcha as to why you shouldn't use it at all. That's insane. I promise that disk spanning issues won't affect your use of it on your tiny ThinkPad SSD. It's important to note that striping and mirroring works just fine…

Good news, it will work just fine on that too.

But RAID-6 is the closest approximation to raid-z2 from ZFS! And raid-z2 is stable for a decade+. Indeed btrfs works just fine on my laptop. My point is that Linux lacks ZFS-like fs for large multi disc setups.

Seriously for the people who take filesystems seriously and have strong preferences... Multi disk might be important.

btrfs was unusable in multi disk setup for kernels 6.1 and older. Didn't try since then. How's stable btrs today in such setups? Also see https://www.phoronix.com/news/Josef-Bacik-Leaves-Meta

How can I know what configurations of btrfs lose my data?

I also have had to deal with thousands of nodes kernel panicing due to a btrfs bug in linux kernel 6.8 (stable ubuntu release).

Damn. I was enjoying not having to deal with the fun of ZFS and DKMS, but it seems like now bcachefs will be in the same boat, either dealing with DKMS and occasional breakage or sticking with the kernel version that slowly gets more and more out of date.

The article says that bcachefs is not being removed from the mainline kernel. This looks like mostly a workaround for Linus and other kernel devs to not have to deal with Kent directly.

Btrfs is the closest in-tree bcachefs alternative.

Suse Linux Enterprise still uses Btrfs as the Root-FS, so it can't be that bad, right? What is Chris Mason actually doing these days? I did some googling and only found out that he was working on a tool called "rsched".

It's orphaned in Debian as well, but I'm not sure what significant advantages it has over btrfs, which is very stable these days.

Absurd to claim it’s unusable without any qualification whatsoever.

Single, dup, raid0, raid1, raid10 have been usable and stable for a decade or more.

Your distro could very easily include bcachefs if it wishes? Although I think the ZFS + Linux situation is mostly Linux religiosity gone wild, that very particula…

I can think of non-religious reasons to want to avoid legal fights with Oracle.
