Kernel Plugin, failure with Proxmox 6.14 and Proxmox 6.13 missing

Mic2024 · Apr 4th 2025

Hello everyone,

I saw that the OMV kernel plugin offers the Proxmox kernel 6.14 for installation. Unfortunately, this kernel is not compatible with ZFS. Are the developers aware of this? A note would have been helpful.

Unfortunately, you can't install the Proxmox kernel 6.13 via the plugin. However, it does offer some improvements that I find interesting, and it is compatible with ZFS. Could you please include this kernel in the plugin?

Thanks and regards,

Mic.

It is compatible with zfs. You must use zfs from the proxmox repo which requires backports to be disabled currently to avoid using backports zfs 2.3.1. This is a temporary problem until proxmox is using zfs 2.3. I don't have a good place to put notes on a plugin that is only a datatable and I don't want to have to release a new plugin every time a tiny dependency changes.

There is no proxmox 6.13 kernel in their repo - http://download.proxmox.com/de…ubscription/binary-amd64/

Got zero issue with Debian GNU/Linux, with Linux 6.14.0-1-pve (contrary to the previous one) and Nvidia recompile to it in a flash.

Hello ryecoaaron ,

I got your point. It may be complicated to implement this information and I also understand that it is just a question of time when ZFS support also will be available for 6.14. Maybe you could mark it in the download menu as "proxmox kernel 6.14 (no ZFS support)" until it is available or you do not implement a new kernel in the plugin until all features of OMV (and OMV extras) is supported.

I have seen there is a proxmox kernel 6.13 available but not in your OMV Kernel plugin. Could you please add it to the download list, so I (or other users) dann install it?

Thank you.

Regards
Michael.

Proxmox kernel 6.14 supports ZFS. You need to use ZFS 2.2

Opt-in Linux 6.14 Kernel for Proxmox VE 8 available on test & no-subscription

We recently uploaded a 6.14 kernel into our repositories. The current 6.8 kernel will stay the default on the Proxmox VE 8 series, the newly introduced 6.14…

If I download the Proxmox Kernel 6.14 in the OMV Kernel Plugin it crashes. If there is a solution, please OMV developers provide an update for OMV. Thank you.

But zfs is supported. That is one of the primary reasons of using the proxmox kernel. Your system just can't compile zfs 2.3.1 from backports on the 6.14 kernel. Since another reason for using the proxmox kernel is to avoid compiling the zfs module, using zfs from backports should be avoid anyway. For your system, you need to disable backports and remove zfs-dkms 2.3.1.

Please look at the proxmox repo link I posted. There is no proxmox 6.13 kernel.

It crashes on your system because backports is enabled and you have zfs-dkms 2.3.1 installed. None of the proxmox kernels need this package.

sudo omv-changebackports no

sudo apt-get purge zfs-dkms dkms

Then click the install 6.14 proxmox kernel menu option.

Mic2024 · Apr 6th 2025

Hi ryecoaaron .

Thank you, to remove zfs dkms was the golden hint. Great. I needed to reconfigure a lot of things but now 6.14 works.

What did I do?

1. In OMV WebGUI: System > OMV extras click on Disable backports

2. Continue in command line (SSH connection):

Code

# Disable backports (via command line):
$ sudo omv-changebackports no

# Remove zfs dkms:
$ sudo apt-get purge zfs-dkms dkms

# Remove unneeded files:
$ sudo apt-get autoremove
$ sudo apt-get autoclean

# Check, if all rests are gone:
$ dpkg -l | grep zfs-dkms
$ sudo dkms status

### Restart the computer now. ###

# Check, if OMV ZFS plugin in still installed.
# (In my case it disappeared.)
$ dpkg -l | grep openmediavault-zfs

# Re-install OMV ZFS plugin:
$ sudo apt-get install openmediavault-zfs

### Restart the computer now. ###

# Check in WebGUI, if your ZFS pool is still available.
# (In my case, it was disappeared, too.)

# Check for your ZFS pool to be imported and its pool ID:
$ sudo zpool import

# Re-iport ZFS pool by ID:
$ sudo zpool import <yourPoolID> -f

# Check in WebGUI, if your ZFS pool is now available.

Now, everything is running again properly but with new Kernel Proxmox 6.14.

I think, I cannot use the OMV standard Kernel with ZFS anymore, right? (But I don't want ro do it.)

Regards
Mic.

Mee, too. Proxmox seeme to be zhe betzer solution.

What would I need to do, in case I would need it again with the standard kernel?

Worry about it then.

Good idea... also if it is often too late, in case I do this. 🤣

But anyhow, if not already done, these hints should be in the documentation of the Kernel plugin. Maybe you find a good way...

Thank you.

Hello ryecoaaron ,

I needed to restore an old installation of OMV7 on my PC and I did the same steps as described above but now I am not able to update the Kernel Plugin. I always get the error:

Code

(Reading database ... 121026 files and directories currently installed.)
Preparing to unpack .../pve-firmware_3.15-3_all.deb ...
Unpacking pve-firmware (3.15-3) over (3.14-3) ...

dpkg-deb: error: paste subprocess was killed by signal (Broken pipe)
Errors were encountered while processing:

** CONNECTION LOST **

What shall I do this time?

[UPDATE]

My solution:
1. sudo apt remove firmware-intel-sound
2. Do the Update...
3. sudo apt install firmware-intel-sound

pve-firmware 3.15-2 Update Fails

An update for pve-firmware 3.15-2 showed up today. I used the GUI to update and I get the following error below. This is a fresh OMV install, I only use GUI for updates, have not installed any other packages via commandline, etc. Ideas?

The preference for the Proxmox kernel will be noted in the ZFS plugin doc, when it's complete.

Essentially the ranking will be:
ZFS with backports Debian kernel - a bad idea. Problems are possible with each kernel update.
ZFS with standard Debian kernel - will work, but not ideal.
ZFS with Proxmox kernel - best case scenario for ZFS.

Hi,

I encountered similar problem but I solved it by manually backporting zfs-dkms 2.3.2 from sid to bookworm.

First, you create /etc/apt/sources.list.d/unstable-source.list containing:

Code

deb-src http://deb.debian.org/debian sid main contrib

And do following to set up the build environment and start backporting

Code

sudo apt update
sudo apt install devscripts build-essential lintian fakeroot
cd ~/zfs-backport
apt-get source zfs-linux/sid
sudo apt-get build-dep zfs-linux/sid
cd ~/zfs-backport/zfs-linux-2.3.2
dch --local +bpo12+1 -D bookworm \
    "Backport ZFS 2.3.2 from sid into Bookworm"  
debuild -us -uc -b

Then the deb files from the backport will be available in ~/zfs-backport. Install them

Code

cd ..
sudo dpkg -i libnvpair3linux_*.deb libuutil3linux_*.deb \
             libzfs4linux_*.deb zfs-dkms_*.deb zfs-zed_*.deb
sudo apt-get -f install
