ZFS 0.8.0 Released

I'm a little to excited about this release... :)

Pardon my ignorance but will this be part of a point release such as say PVE 5.4.1 or what?

while I wholeheartedly support and approve leaving ZFS 0.8 in test for an indefinite timeframe, it would be desirable to include an upward migration to ZFS 0.8 for PVE 5.x, if for no other reason that SIMD acceleration is currently not supported for Linux 5.0 and newer kernels (https://github.com/zfsonlinux/zfs/releases/tag/zfs-0.8.0)

While I'm not in a hurry to deploy a x.0 release and this may get fixed, its conceivable that performance will be better on older (than 5.0) kernels. besides, unless you're planning to deprecate support for pve5 anytime soon you may want to add support in any case.

Yeah, the no-SIMD acceleration is pretty bad. Hopefully proxmox dev's will revert the corresponding commits and restore the usage of kernel_fpu for any kernel (for reference: ZFS issue #8793, NixOS article and their revert commit).
 
I just read about Linux kernel 5 are not exporting checksums functions. What is the future for Proxmox and ZFS going forward?

Thanks
Felix

afaik only when using encrypted ZFS there could be issue's, plus once could custom build there kernel to overcome this.. (custom build kernel is already being used by proxmox)

Please add ZFS 0.8.1 to Proxmox 5.x or Release Proxmox 6.0 as soon as Debian/Buster comes out.

It will get our machines so much performance gain and TRIM for SSD's whitch is very important.
 
I'm pretty sure this is not the way to get features into PVE ;)

The guys at Proxmox are quiet up to date with bleeding edge technologies and are aware of the new release already. Also they stated it will be delivered after testing has shown that it's possible.

To keep up the awesome work, just buy some more subscriptions to keep it spinning.

There's work underway upstream to reimplement the functionality without relying on the fpu symbol export: https://github.com/zfsonlinux/zfs/pull/8965

Once this is merged the algorithms should again have access to the SIMD instructions.

hope this helps!

I noticed the SIMD changes have been merged on the ZoL side. Is there a ballpark for when these will make it into proxmox, even proxmox beta? Thanks!
