Raidz expansion feature?

[Gandalf-the-Blue]

Hi,
The openzfs raidz expansion feature looks almost ready to go now, considering all reviewers have okayed it and only final code cleanup and tests cleanup is left.

What are the plans to integrate this into the plugin?

[ryecoaaron]

None at the moment. Until zfs 2.2 is in the Debian repos, it couldn't be added to the plugin anyway. If zfs 2.2 is added, you can still use raidz expansion from the command line.

raidz expansion won't be in the 2.2 release. It should be in the next release, 2.3 but that is at least 1 year away, maybe even more. Looks at the current 2.2 release that was originally scheduled for early this year and just made it in October, I'd say 1,5 years.

Which means it would be in Debian months after that. So, this will probably be an OMV 8.x feature lol

BTW, it can be done if you want to manually compile Don Brady's OpenZFS branch containing the expansion code.
I did it and was able to integrate it into TrueNAS (it was a nightmare and I didn't document it well enough to share it).
But it can be done so you can use the CLI to add individual disks to your a RAIDZ pool, if you're dedicated enough (and willing to risk it for the biscuit).

Zfs 2.3 ist officially released. Now it should be tested and be shortly released in the Backport.

By the way: the "enable backports" function in the omv extras tabs seems not to work. I pressed it, but my packages still remains at stable version.

I would imagine 2.3 will be in sid/unstable for a while before it is in backports.

Open a thread on the forum and post the output of the button. Enabling backports does not automatically upgrade packages to the backports version.

I am not sure. 2.2.7 was released to backports 2 weeks ago and released on github 4 weeks ago 👍

Maybe it could be in backports in around 2 weeks

Oh ok. I will do that.
Hopefully hitting the right thread :D
How is the enabling backports button supposed to work? I thought I have to hit it and then I can update the specific package on the web UI.

No, not at all. Version 2.2.7 is just a patch release, which is typically fast-tracked to backports since it’s often necessary for compatibility with newer kernel versions. On the other hand, 2.3 is a major update, so it’s more likely to take around six months before it appears in the backports.

The backports button basically just enables the repo, pins zfs*, and runs apt-get update. If apt/dpkg thinks there is a backports package to update to, it will show up in the Updates tab. If the pinning on your system is not standard, then you won't see any updates. This can be discussed further in a thread on the forum.
