There’s been some Friday night kernel drama on the Linux kernel mailing list… Linus Torvalds has expressed regrets for merging the Bcachefs file-system and an ensuing back-and-forth between the file-system maintainer.

But scrub is not fsck. It just goes through the checksums and corrects if needed. That’s why you need ECC ram so the checksums are always correct. If you get any other issues with the fs, like a power off when syncing a raidz2, there is a chance of an error that scrub cannot fix. Fsck does many other things to fix a filesystem…
So basically a typical zfs installation is with UPS, and I would avoid using it on my laptop just because it kind of needs ECC ram and you should always unmount it cleanly.
This is the spot where bcachefs comes into place. It will implement whatever we love about zfs, but also be kind of feasible for mobile devices. And its fsck is pretty good already, it even gets online checks in 6.11.
Don’t get me wrong, my NAS has and will have zfs because it just works and I don’t usually need to touch it. The NAS sits next to UPS…
I have never had an issue with ZFS as long as there is a redundant copy. A bad ram might cause an issue but that’s never happened to me. I did have a bad motherboard that corrupted data on write. ZFS threw its hands up but there wasn’t any unfixable corruption
