Update from OMV6 to OMV7 can't get Proxmox kernel working

I upgraded my OMV6 system to OMV7, I did have some issues with the upgrade but got everything to work again and boot however ZFS was no longer working. I tried installing both proxmox kernel 6.2 and 6.5 however my system will not boot when I select these kernels. I really would like top avoid reinstalling again to get everything working. I have the system up with the following kernel Debian GNU/Linux, with Linux 6.1.0-18-amd64. Any suggestions on where I can look to find the cause of the boot issues because the boot output doets not give anything

I get a 500 error that the zfs module is not loaded and should try modprobe, I tried but it says that for the native omv kernel it can't get the module for zfs.

The systems with the proxmox kernel is that it loads the nvme drive then thats it, nothing goes any further. Hard to explain, journbelctl says nothing

The problem is not exactly zfs, I have found that the proxmox kernel works better and more reliably without breaking my zfs pool and that's what I would like to get working again. I will try later tonight again after purging the nvidia drivers to see if that helps to get the proxmox kernel installed. I have removed the openmediavault-zfs plugin because when installing the proxmox kernel it gave an error with the zfs plugin installed.

Thanks I will give the outputs once I have reinstalled openmediavault-zfs again. Will update with the output as soon as I can

The feed back I asked for would be helpful, as I believe I may have found a bug in installing pve kernels in some cases.

There is the output of the requested commands, zfs tab still says:

As stated above, I am unable to boot using a pve kernel. I'm still using the Debian GNU/Linux, with Linux 6.1.0-18-amd64 kernel. Both pve 6.2 and 6.5 kernels install successfully no problem but when I boot to them they do the initial ramdisk load then switches to saying /dev/nvmensp1 clean 5788474/7748489493 blocks or something like that on the attached monitor console output and doesn't go any further, I am not sure how to better explain the issue, appologies.

Thank you for your reply and patience, I appologies as I am knowledgeable with Linux but certainly not an expert yet at diagnosis on these matters. I will send you the screenshot of the WebUI tab "System > Kernel" once I get home today from work. Is there any other information I can give you that might help? Could it be that both 6.2 and 6.5 kernels do not like my GT710 Nvidia GPU? I have also done nano /etc/defualt/grub and removed the quite part from it to get output from booting the 6.5 kernel to better understand whats going on. How long should I wait before I force the system to power down again when I test the 6.5 kernel again? My monitor is connected to the GPU hdmi output

You've cross posted with the same question elsewhere. This thread is not relevant to you if you start with pve kernel +zfs + omv

Also I was running Proxmox kernel + zfs + OMV6, upgraded to OMV7, could not get zfs working, couldn't boot into pve kernel after upgrade

Thank you Krisbee for your help, I did as you suggested and noticed that the system got stuck at nvidiafb: Device ID: 10de128b so as I figured it was my old Nvidia GPU that was holding back the boot process, did some googling and found others had a similar problem so I did as suggested and replace "quiet" with "nomodeset" and that got it to boot using the pve kernel 6.5. After that I installed the correct driver for my GPU and now it is working as expected, imported my zpool and now have access to my drives. Thank you for your assistance.
