problem update omv then zfs

fogia-f · Sep 8th 2025

Hello, a quick panic message: this morning I updated the omv packages and something didn't work, I had this message in the logs

>dpkg: dependency problems prevent configuration of linux-headers-amd64: linux-headers-amd64 depends on linux-headers-6.12.38+deb12-amd64 (= 6.12.38-1\~bpo12+1); however: Package linux-headers-6.12.38+deb12-amd64 is not configured yet.

So I asked Claude how to solve this, and he suggested the following, which I did:

>sudo apt-get remove --purge linux-headers-amd64 linux-headers-6.12.38+deb12-amd64

>sudo apt-get update

>sudo apt-get install linux-headers-amd64

And now I'm panicking. First, I got an error on swag that gave me this message:

>“ssl\_stapling” ignored, no OCSP responder URL in the certificate "/config/keys/cert.crt

which I managed to resolve using a Duplicati backup. Now for my moment of panic: my server has five hard drives: a system disk where I have my comps, a disk dedicated to Frigate, and three large disks for my data in ZFS with . And then when I go to the OMV management interface on File System, I get this message:

>No file system backend exists for type ‘zfs’.

I have six shared files (Nextcloud, Books, Music, Photos, Backup, Surveillance, Videos). Is there a way to recover all of this (I think the data still exists, but I don't know how to access it)? I can manage with the photos because I have an external copy (which is the most important thing), but my backup of the videos is six months old and I've added quite a few things since then. I don't have any other backup of the documents I have on Nextcloud (although most of the documents that haven't been updated are actually available on my computer). So, in short, is there any way to save the situation?

Another point that may explain it: I can't find the zfs extension in omv

So I naively think that if I manage to reinstall the zfs package, maybe everything will go back to normal

But I can't find the openmediavault-zfs package. When I go to the omv-extras tab on the omv GUI, I just see a docker repo that is checked. In the extensions, I see that omvextrasorg 7.0 is installed. So for now, I'm not deleting anything, I'm not formatting, but I'm pretty anxious...

The zfs plugin doesn't need the docker repo. If omv-extras is installed, then the zfs plugin should be available. What is the output of the apt clean button in omv-extras?

For some reason, your system doesn't like the omv-extras gpg key. Try the apt clean repos button and post any errors.

ok it worked, now i just re-installed zfs and when I go in the system file page, I see 3 lines : one with my system hard disk et 2 lines with nothing but "missing" at the right. What should I do ? Mount an existing system file on each of the lines ?

What should I do ?

Click the Discover button in the zfs plugin.

The Discover button is on the Pools tab. Looks like a magnifying glass with a + in the middle

when I go in each one I have a red message :

Your system failed to compile or load the zfs module. It tells you what to do. sudo modprobe zfs or just reboot. If the compiling worked, either of these should just work. This is one of the biggest reasons I tell people to use the proxmox kernel available in the kernel plugin.

ok I did sudo modprobe zfs and I got this : modprobe: FATAL: Module zfs not found in directory /lib/modules/6.12.38+deb12-amd64

I tried to reboot and the same

the module failed to build then. As I mentioned above, the proxmox kernel avoids needing to build the module.
