On ubuntu 22.04 the kmod module is not correctly loaded at boot by default

[Nottt]

In a clean ubuntu 22.04 install i followed install instructions with a 6.8 hwe kernel.

After rebooting and trying zfs --version I get a message zfs_version_kernel() failed; No such file or directory

I can fix this with modprobe -r zfs and then modprobe zfs.

But after rebooting again the issue persists. I fixed it by adding zfs to /etc/modules.

Is this expected ? or should be there a better way to fix this?

Not expected. We actively test on 24.04 and haven't seen any issue loading it up on boot.

Is that still a problem?

[Nottt]

Yes, still happening

That's interesting because I just checked and I have a bunch of production servers using this package on Ubuntu 22.04 LTS. Though on those systems I'm also using https://github.com/zabbly/linux on the kernel side, so not sure if that's what's fixing this.

I still suffer from the same issue in a recent fresh install I did just today, I use the standard linux-generic-hwe-22.04-edge package kernel.

And it happened with multiple kernel versions so its not related to the version, and should be easy for you to reproduce...

Also btw seems the script is now building 2.2.7 instead of 2.3.0 any reason for that?

[stgraber]

Yeah, ZFS has a terrible track record on their .0 releases ;)

[Nottt]

What do you mean ?

[stgraber]

The first micro release of a ZFS minor release often has some bad bugs that may cause crashes or data corruption, so I tend to wait for the first point release (2.3.1 in this case) before pushing it to users

Keep the good work we appreciate it <3
