[Tamas Papp]

ZFS v0.7 is out, current version is 0.7.3:

https://github.com/zfsonlinux/zfs/releases/tag/zfs-0.7.3 .

It is desired to have the latest stable version at least in LTS.

I've been preparing 0.7.3 for Bionic this week. Once the kernel is released with the updated drivers in the package I'll release the updated user space tools.

[Tamas Papp (tomposmiko)]

Awesome!

[Colin Ian King (colin-king)]

Patch submitted to kernel team mailing list for review and application to Bionic:

I have a related question... as far as I'm aware, the ZoL kernel<->userspace interface is still not versioned: https://github.com/zfsonlinux/zfs/issues/1290

Effectively, this means that the version of zfsutils-linux must always match the version of the kernel modules. What is the plan to handle this in Ubuntu's HWE kernels? For example, if Bionic gets ZFS 0.7.3, will that show up in the Xenial HWE kernel? If so, that will create an incompatibility, unless zfsutils-linux is updated in Xenial. But if zfsutils-linux is updated in Xenial, then it will be incompatible with the Xenial GA kernel.

Bump the version.

The current version is 0.7.5:

https://github.com/zfsonlinux/zfs/releases/tag/zfs-0.7.5 .

ZFS 0.7.5 is compatible with 2.6.32 - 4.14 Linux kernels.
ZFS 0.7.3 was compatible with 2.6.32 - 4.13 Linux kernels.
ZFS 0.6.5.11 was compatible with 2.6.32 - 4.12-rc3 Linux kernels.

[Tamas Papp (tomposmiko)]

Current Bionic kernel still contains 0.6.5.
When can we expect 0.7 to land?

[costinel (costinel)]

this is really worrying. we chose ubuntu for native zfs but it is such a dissapointment to not provide at least a ppa with updated zfs 0.7 for xenial.
if next LTS comes without 0.7 we will switch back to centos that has almost immediate release packages after official release.

0.7.4 has landed into Bionic (very stable coming LTS)
https://launchpad.net/ubuntu/+source/zfs-linux

[Colin Ian King (colin-king)]

We can expect the update ZFS kernel drivers to land once we have an update 4.14/4.15 kernel landing in Bionic. However this has been delayed because of the Spectre/Meltdown fixes. Apologies for the delay, but we do want to ship kernels that are in good shape into the development release.

[Sam Van den Eynde (samvde)]

What is the policy for ZFS release updates? Are they limited to LTS releases? Will all HWE kernels get upgraded eventually?

As an example, would Xenial eventually see ZFS 0.7 or even 0.8 or 0.9 ?

[Richard Laager (rlaager)]

16.04's HWE's updates will top out at the kernel version shipped in 18.04. I assume this is because you can then just use 18.04.

[Sam Van den Eynde (samvde)]

Yes, but what does that mean wrt. supporting ZFS releases? Are major upgrades considered for all currently supported HWE kernels? The current LTS kernels? Only future/next LTS kernels? What is the policy?

[costinel (costinel)]

@ comment #9, it has landed into proposed, not into main! this means xenial won't get 0.7 via hwe... :(

[Garrett Fields (fields-g)]

Version bump? zfsonlinux 0.7.6 released.

https://github.com/zfsonlinux/zfs/releases/tag/zfs-0.7.6

[Colin Ian King (colin-king)]

I'm waiting for 4.15 to land in Bionic, once that has happened I'll re-spin the pending 0.7.5 to 0.7.6

[Launchpad Janitor (janitor)]

This bug was fixed in the package zfs-linux - 0.7.5-1ubuntu2

---------------
zfs-linux (0.7.5-1ubuntu2) bionic; urgency=medium

  * Bump version and re-upload
