Bcachefs Squeezes More Fixes Into Linux 6.12

[intelfx]

Failing to clear the queue of operations during a shutdown shouldn't cause problems. System crashes aren't know to clear queues.

If a CoW filesystem can't deal with that, it's not worthy of the title.

It's not on-disk data consistency problems, it's in-memory kernel data structure consistency problems. Like use-after-free.

This filesystem has a true opportunity to unseat ZFS at that niche in a way that btrfs has failed to do, glad to see it's got momentum. I don't understand why Torvalds is being such a drama queen about its pace of development.

not gonna happen for decades if ever. openZFS is ROCK solid with FAR more users, for a FAR lengthier time period, along with a FAR larger development 'team'...

That said I have been running bcachefs on my framework13 nb w/cachyos... nothing noticeably catastrophic ... yet ... but it only gets light usage to moderate usage now and again, especially since it's the original 11th gen mainboard and the coin cell appears to have mostly givern up the ghost right now, so sometimes it boots, sometimes it needs to sit on a charger for a day or so, and sometimes we do surgery... I really need to order a replacement...

(Also the above said, I have BTRFS on endeavour(m.2 SSD 9th gen) and opensuse TW(hdd) and those have been equally fine, although they are both single disk setups... migrating my NAS will be moving from EXT4 to openZFS on Ubuntu server... with the potential of perhaps migrating to nixos if I get comfortable enough with it, or if Ubuntu forces me to do so...

Nixos has a more 'native' openZFS support w/o DKMS... but I have not delved too deeply into it yet, as frankly, I have not done much w/nixos yet other than a fairly useful desktop config... then I stopped waiting to see if flakes were a better way forward or the 'old' way, so that project is stalled out for the moment... (I'm not really sold on immutable stuff... all versions so far are klunky, and TBH a balky PITA... mostly nixos and some of the Fedora based immutables and Aeon(I find Gnome unusable w/o HEAVY modification...) here... ubuntucore seems like its needs more baking time, but might be more promising overall as it should be more flexible v. Fedora, microos/AEON variants... nixos should be close though if I spent the time on it... at least w/flakes I think...)

I do a lot of zfs deployments and Ubuntu is by far the best Linux distribution for it.

i guess you never tried nixos.

Nobody uses nixos on the enterprise.

doesn't change the fact that nixos has the best zfs support.

[royce]

In your opinion.

Are there plans to update the equivalent of a 4 disk RAID 10 layout to be able to survive 2 disk failures like you can in a traditional RAID 10 if the failures are one each in different mirrors? Total loss with any 2nd disk failing is a non-starter for me.

No RAID10 is immune to two disk failures if the failures happen to be the right... Or rather wrong disks.
