ZFS 0.8.0 Released

[ndoggac]

ZFS 0.8.0 has been released. Includes native encryption, ssd trim, directed I/O, sequential scrub and resilver, etc.

https://github.com/zfsonlinux/zfs/releases/tag/zfs-0.8.0

This is a pretty huge release. What's the normal turnaround time for a ZFS release to integrate into a Proxmox release?

Patches already landed on the pve-devel list:

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?

You will see ZFS 0.8 in the upcoming Proxmox VE 6.0.

 

[alexskysilk]

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.

Includement in / For PVE5.x would be greatly appreciated...

If not possible, what is the release plan for 6.0? 6+ Months?

I guess the release will depend on Debian Buster, as long as it is not released PVE 6 won't come either.

Another vote to deploy it for PVE 5. We have a petty important issue where our hypervisor sometimes lock up because of ZFS and requires a reboot. They added a new config in 0.8 that try to send the hung I/O again (since it's hard to pinpoint what is causing this).See here: https://github.com/zfsonlinux/zfs/issues/7038#issuecomment-474640183
This would fix our issue.

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

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)

Release date
============

We plan to release on 2019-07-06. (read: 6th of July 2019)

If you want to celebrate it, please consider attending a Debian release
party, or hosting your own! See
https://wiki.debian.org/ReleasePartyBuster for more information.


What is the planned release date for proxmox? is there much wore to be done to get it all working with debian 10?

 

[yarii]

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.

 

[mailinglists]

If thi is a feature request it is +1 from me.

 

[morph027]

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.

 

[dendi]

I also prefer to wait a bit more and avoid problems ;-)

 

[Breymja]

Any info regarding https://github.com/zfsonlinux/zfs/issues/8793??

 

[Stoiko Ivanov]

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!

https://forum.proxmox.com/threads/proxmox-ve-6-0-beta-released.55668/

it contains ZFS 0.8.1, works like a charm for me

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!
