Proxmox Kernel Panic

Hi guys!
I have two servers running OMV with ZFS the first of them I have just upgraded to the latest 0mv version and chose the Proxmox kernel without problems and installed ZFS no problems.....no problems adding pools etc...
Server number 2 is a purpose built server with the following hardware:

Chassis: Fractal Design Define XL R2 Black Pearl

Mobo: ASUS X99-M WS/SE, Socket-2011-3

CPU: Intel Xeon E5-2620 V4 Processor

Samsung - DDR4 - 32 GB - DIMM 288-pin 2400 MHz / PC4-19200, CL17, 1.2 V, ECC

System Drive: Samsung 960 EVO 250GB M.2 PCIe SSD

Cooling CPU: Noctua NH-D15

PSU: XFX 850W Semi Modular

I haven't researched the fact wether my hardware is supported...perhaps someone here has the info on that....
I updated and upgraded OMV 4 to the Proxmox kernel and then rebooted to remove the other kernel installed but got kernel panic....
I reinstalled and updated and upgraded to latest kernel Linux4.19.0.bpo.4-amd64 and rebooted but got kernel panic....tried to boot to Proxmox recovery but had a long list of what I assumed were hardware issues with a green background and nothing....
I can boot to the latest kernel - but am wondering how to find out what is the problem for the kernel panic if I can't even get to recovery mode....
Can someone give me some pointers as to what I can do?

HI ryecoaaron!

Sorry, sorry and sorry...forgot to say I am doing a test install without my m2 and other drives connected....
Have a few live cd's floating about just not sure what to look for...not my strong point kernel problems...

well it boots the standard kernel...just not the proxmox?

Thanks mate
I shall set up that one instead...will comment here when I have had time to do so.

Hi again!

This proved to be a pain in the bum....

On this computer I thought I would be smart and install a test scenario on an ssd I had lying around...now as stated above I could get it to boot to the latest kernel but not proxmox....getting rid of the proxmox kernel after installation also pain in the bum.... it didn't show up as a listed boot kernel even though it was installed and showed on startup....

I thought to hell with this and reinstalled OMV 4 again so that I had a clean installation...I then updated it with all updates....I installed the openmediavault-omvextrasorg_latest_all4 package...

I had previously tried to install the zfs plugin but that gave lots of errors files missing etc....

Instead I installed zfs from command line with all dependencies as according to zfsonlinux:

Install the kernel headers and other dependencies:


# apt install --yes dpkg-dev linux-headers-$(uname -r) linux-image-amd64






Install the zfs packages:
# apt-get install zfs-dkms zfsutils-linux

I rebooted and tested that zfs was working by just running:

# zpool status

This gave me no pools available...

I then installed the zfs plugin and imported my pools without issue...sort of....more below

I added my smb shares etc and then cloned the drive with clonezilla.

Now one thing I hadn't thought of when I was going to import my pools is the fact that the ssd drive was taking up a sata connection and I didn't have others available when all drives containing my pools were connected.

I got over this little hiccup by connecting the ssd drive to an adapter ssd to usb and connected and booted from that so that I could connect all my drives for my pools...

In principle my work was done and it was working normally.....but....

I thought I would try and upgrade the existing installation on my m.2 from omv3 to omv4.....but this went pearshape in a big way....so having my clone as back up I tried to do a new installation on the m.2 and that proved to be a pain in the bum in a big way....despite having done the same procedure ass the standard ssd I got errors when trying to install the zfs plugin.....it had dependency problems but all dependencies were installed....?! I gave up on that and added my image I had cloned from the ssd and everything is hunky dorry...?

Two exactly the same installations but one caused problems and the other didn't?!

I will point out that I tried and failed after several attempts to install to a usb flash drive ...the same one I had used for the other server running zfs.....it would not install kept failing around 36%....?!

This little exercise has cost a bit of time and well forget the hair pulling don't have much to pull these days....lol

This is the thing I love and hate about linux....sometimes things go so easily you wonder what you did wrong.....and other times it gives you a challenge....

All well and ends well until the next time....;)
