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?

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).
