Problem with new OMV7 kernel update

Mic2024 · Feb 18th 2025

Dear Experts,

OMV offered me a big bunch of updates today and I let the install but it seemes there is an problem with the new kernal. I get the following error messega at the end:

Code

It seems the new kernel has an incompatibility with the ZFS plugin of OMV-Extras. I also tried to make the update on the command line but the result is the same issue.

My kernel version (after performing the update):

Code

# uname -r
6.1.0-31-amd64

What can I do to fix it?

Regards

Mic.

It is not able to reboot with the new kernal:

justhearforthesnacks · Feb 19th 2025

I'm having the same issue, with the new updates, also using zfs. Restored from a backup this morning.

stahelp · Feb 19th 2025

I have exactly the same problem, can not boot after the upgrade.

Any help is appreciated

ryecoaaron · Feb 19th 2025

you must have an old version of zfs that won't compile on the 6.12 kernel. Using the proxmox kernel solves this problem. If your system won't boot, you need to connect a monitor and keyboard and select an older kernel.

stahelp · Feb 19th 2025

Thank you so much for your quick reply.

I was able to boot the system with kernel 6.1.0-31 recovery it looks fine.

I will now install the kernel plugin and find out which combination of proxmox kernel and my zfs version 7.1.1 matches 6.1.0-36.1.0-311

Mic2024 · Feb 19th 2025

Hello,

I don't use Proxmox... only OMV7 as you can download it.

The problem is that the update was offered via OMV and I also use the ZFS plugin from OMV-Extras. In this case, an update for the ZFS plugin was either forgotten to be offered or the OMV update was rolled out too early.

I also took the detour via the recovery boot yesterday and then selected the kernel without amd64 in the name to boot menu. After that, I was able to downgrade to the old kernel 6.1.0-31-amd64 and was bootable again.

Today, however, OMV showed me in the plug-in settings that my ZFS plugin was not installed. So I ran the installation again via the WebGUI. It tried again to install the new, faulty kernel 6.12.9+bpo-amd64.

The system now boots and my ZFS pool is accessible, but I think that the problem will keep occurring until an error-free combination of updates (kernel + ZFS plugin) is offered in OMV.

Thank you.

Regards,
Mic.

Suggestion is to use the proxmox kernel, not proxmox as such.

You can install the proxmox kernel from the kernel plugin. The advantage of the proxmox kernel is, that it supports zfs out of the box.

How does this cooperate with the OMV-Extras ZFS Plugin? Which Kernel-Version of Proxmox is recommended to be used?

Well. The plugin is the reason why the proxmox kernel has been made available by the kernel plugin.

reycoaaron is the developer of both plugins and all others from omv-extras

Quote from Mic2024

Which Kernel-Version of Proxmox is recommended to be used?

I use 6.8 (and do not use zfs). reycoaaron uses 6.11 according his signature. Have not seen any posts regarding issues with 6.11.

So I would think you are good to use the latest one which is 6.11 at the moment.

Mic2024 · Feb 19th 2025

I am also not able to install the OMV Kernel Plugin:

macom · Feb 19th 2025

Did you check if it is installed?

Any message when clicking the bell icon in the top right corner of the GUI?

You posted two screenshots from diskstats plugin. How is that related?

Valsi · Feb 19th 2025

is this a similar issue as last week with the "apt upgrade → Size + hash Sum mismatches"?

Got today also many updates and want to prevent the same disaster (new installation)

Mic2024 · Feb 19th 2025

It is more complicated as I expeced:

1. Uninstall the faulty ZFS Plugin in WebGUI

2. Uninstall the faulty Kernal Plugin in WebGUI.

3. Purge all installed dependencies (command line, SSH)

4. Reboot Computer

5. Install Kernal Plugin

6. Install Proxmox-Kernal. I have selcted: Debian GNU/Linux, with Linux 6.11.11-1-pve

7. Make new Kernal to "boot kernal" in WebGUI

8. Reboot Computer

9. Check if correct kernal was activated (command line, SSH): uname -r

10. Install ZFS Plugin in WebGUI

11. Remount ZFS-Pool (command line, SSH)

Now it works. I am back in the game. Thank you. 😊

I wouldn't call a new installation a disaster.

This issue should not apply to you. This is about amd64 not arm.

This is how it began at my system yesertday. Do you use ZFS? Than maybe you could also switch to the Proxmox kernal bevore you start doing the updates.

I recommend you to have a display and a keyboard available...

Mic2024 · Feb 19th 2025

After my change to the Proxmox Kernal I see now a lot of available Updates in OMV. Should I install them or levae them?

- grub-common 2.06-13+pmx2

- grub-efi-amd64 2.06-13+pmx2

- grub-efi-amd64-bin 2.06-13+pmx2

- grub2-common 2.06-13+pmx2

- shim-helpers-amd64-signed 1+15.8+1+pmx1

- shim-signed 1.44+pmx1+15.8-1+pmx1

- shim-signed-common 1.44+pmx1+15.8-1+pmx1

- shim-unsigned 15.8-1+pmx1

- smartmontools 7.3-pve1

Could I run introubles again by installing them?

Install them.

You only need to check with next kernel updates, and before rebooting that the default kernel to boot is set proper on the kernel GUI page.

It happens that the default changes to something different.

It happened to me that the default was "memory test".

If I had rebooted, the device would stay there until a monitor and keyboard had to be connected to boot again with the proper kernel.

This is refered on the wiki page.

Successful. System is after installing the updates and reboot still alive.

Pinning kernel to backports installs 6.12.9+bpo-amd64 resulting in zfs modules failing to build against zfs-dkms version2.1.11-1+deb12u1.

This can be solved be installing updated version of zfs-dkms ( and dependencies) from backports without need of pve kernel then the update can complete.
