zfs-linux upstream at 2.1.4, jammy has 2.1.2

[satmandu]

I know Jammy is in freeze

zfs upstream is now at 2.1.3, which has a lovely set of fixes for issues I have noticed (such as zfs complaining when waking for sleep, and also patches to support 5.16 better and also for the support of 5.17.)

Please peruse the large number of important patches, which will make supporting this in LTS much easier:
https://github.com/openzfs/zfs/pull/13063

I'm running a version of https://launchpad.net/~jonathonf/+archive/ubuntu/zfs built for 2.1.3 on Ubuntu mainline kernel 5.17-rc8 on multiple Jammy-dev systems, and it works beautifully.

I have attached the debian dir I put on top of the 2.1.3 source release which I used to generate debs for this release, which I have tested on a server and client desktop x86_64 machine running Ubuntu Jammy 22.04 (as of March 14, 2022). I am having no zfs related issues.

Status changed to 'Confirmed' because the bug affects multiple users.

Here's a ppa with working packages: https://launchpad.net/~satadru-umich/+archive/ubuntu/zfs-experimental

Yes, would be really important to still get the fixes in zfs-2.1.3 into jammy. I'd love to see that too!

It seems like something has happened with regards to zfs 2.1.4 by looking at https://code.launchpad.net/ubuntu/+source/zfs-linux

[Timo Aaltonen (tjaalton)]

that's just automatic import of current debian

Please note that in jammy we ship cherrypicks of stable branch updates up to zfs-2.1.2-27-g1009e60992

meaning we do have v5.17 kernel support availabe in jammy. Upgrading to complete 2.1.3 / 2.1.4 is something very useful to do, but not sure it can be achieved in time for 22.04 LTS GA, but hopefully will be able to deliver it as an SRU.

[satmandu (satadru-umich)]

Since the 2.1 branch is itself cherry-picks of updates backported from zfs master, it might make sense to just follow the 2.1 series for jammy, as opposed to re-cherry-picking from the upstream cherry-pick backports to the 2.1?

Otherwise, there will be a lot of duplicated work...

The zfs-devs appear to be pretty conservative with what they choose to backport...
