Ubuntu ZFS support in 19.10: introduction

- Mic92 7y agoDoes the ubuntu kernel also comes with the patch that enables vectorized cpu extensions/AVX/AES-NI for zfs these days? https://www.phoronix.com/scan.php?page=news_item&px=NixOS-Linux-5.0-ZFS-FPU-Drop https://www.phoronix.com/scan.php?page=news_item&px=NixOS-Li...
- new_realist 7y agoThis has been “fixed” in upstream ZOL, but Linus should be ashamed.
- jorangreef 7y agoThe linked article is a good example of where choosing a cipher such as ChaCha20-Poly1305 can be a fraction slower than AES but also more reliable and forward-compatible when CPU extensions are suddenly switched off. Imagine the not-too-distant future where a Spectre-like bug forces kernels to disable certain CPU extensions, and you suddenly find yourself stuck with mountains of data encrypted with the wrong cipher that only works safely and tolerably when hardware-accelerated.
- nickik 7y agoI have been waiting for ZFS Native encrypted root. Very nice that this is comming.
- tomatocracy 7y agoYes, though it’s a shame that ZFS native encryption doesn’t support multiple pass phrases/key files to unlock yet (the on disk structure does support this but the utilities don’t and won’t until a future release). That’s the feature that keeps me tied to LUKS+zfs for now.
- radiowave 7y agoHave been booting proxmox machines off ZFS for a few years now, and the only bad experiences have been with grub. Troubleshooting at the intersection of grub and ZFS is..., well..., giving up and reinstalling is usually quicker. So I'm hopeful that Ubuntu's focus on ZFS boot will eventually lead to some of these issues being ironed out.
