Hi all. Has there been any discussion about this here yet? theregister.com/2023/11/27/openzfs_2_2_0_data_corruption

There has. It's not clear illumos ZFS is vulnerable to this. I've tried the reproducer multiple times thus far without reproducing. We don't have reference-copy in illumos ZFS, which appears to be the main way to induce such corruption.

I won't rule the possibility out entirely just yet, but I'm not as worried as the OpenZFS folks.

danmcd Thanks for your reply! That's promising, and good to hear. Is that because ZFS on illumos is a different beast to OpenZSF on other platforms, or are we "just behind"?

both, actually.

Mostly "just behind" but we've cherrypicked from time to time.

:-) Nothing's perfect, I guess. I'll keep my fingers crossed for illumos immunity and that the fix isn't far away for those running ZFS on platforms that are affected.
