New Packages required for CentOS 8.3

[rearden888]

Describe the feature would like to see added to OpenZFS

New packages required now that CentOS has updated it's point release to 8.3.

I'm not sure if this happens automatically, or if this issue needs to be submitted, but now that CentOS upgraded to 8.3, I believe that a new package needs to be released for the current version.

How will this feature improve OpenZFS?

Allow ZFS to be installed onto CentOS 8.3

Additional context

Again, I'm not sure if this needs to be handled manually, but I don't think there is a package available to install kABI packages onto CentOS 8.3. At least, I can't find a download link for that version at:
https://openzfs.github.io/openzfs-docs/Getting%20Started/RHEL%20and%20CentOS.html

Compilation also fails if you're not using kABI packages.

Granted, 8.3 JUST came out, so I'm not really too salty about it, and you can always just keep running the previous kernel for the moment, but it does need to get fixed.

Thanks for the heads-up, I'll roll some 0.8.5 packages for Centos 8.3.

Centos 8.3 kernel interfaces changed 😬 😢

RHEL 8.3 equivalent bug: #11195

So it's not going to work without a patch. It sounds like 2.0.0 works on Centos 8.3 though.

[rearden888]

I suppose there would be pushback on upgrading ZFS major versions to 2.0.0 within a CentOS release cycle. Personally, I'm all for it, but I'm not sure how others would feel about it. In the meantime, it might be worth a notice on the documentation that there aren't currently packages available for 8.3 if it's not a quick fix to build them.

Is there an option to package up 2.0.0, for people who want to upgrade? I don't really know how to do that, otherwise I'd try to help.

[rearden888]

From reading that thread, doesn't it concern packaging for Debian/Ubuntu, not CentOS?

Are there any plans for publishing an official 2.0.0 RPM for CentOS?

[imilne]

Is it safe to move from 0.8.x to 2.0.0? With existing zpools etc?

[rearden888]

I've upgraded several pools from 0.8.5 to 2.0.0 with no issues. Admittedly, they are all pretty vanilla, mass storage volumes, but I haven't had any problems. So, in my opinion, it is, but I don't have massive deployments or anything. By releasing it as a full, stable version, my interpretation is that OpenZFS regards it that way, as well.

Thanks, that's good to know. I'm currently trying to juggle a move to CentOS 8.3 for a system that relies on both ZFS and BeeGFS - both of which are suffering from these kernel changes. I can see us playing it safe and sticking with 8.2 until after the new year.

playing it safe and sticking with 8.2

Keep in mind that you can still upgrade to 8.3 and just continue running the previous kernel (4.18.0-193.28.1.el8_2.x86_64) until the ZFS update drops. This way you benefit from the other improvements in 8.3.

This is what I've done for several servers I administrate and I haven't seen any issues.

We just did this to our servers as well. We updated to 8.3 but set it to use the older kernel with grubby --set-default /boot/vmlinuz-4.18.0-193.28.1.el8_2.x86_64.

[ziggythehamster]

With 0.8.6 having just dropped, including this repo, I think this issue is resolved, right?

[stuartthebruce]

Is a 2.0.1 release needed as well?

[tonyhutter]

I believe this has was resolved awhile ago. Please re-open if it's still an issue.
