OMV ZFS 5.0.6 armhf plugin fails on Pi4 / PiOS 64 Bit 5.10.60-v8+

dubbers · 1. September 2021

Has anyone else tried this combination and succeeded? And if so how?

I've built the Pi4/64 bit Ubuntu Server/ZFS with no problem - but miss the nice webgui of OMV.

I'm assuming that the control file ZFS armhf is likely the starting point of the error above.

Did you follow the guide to install OMV? Installing OMV5 on Raspberry PI's, Armbian SBC's, & i386 32-bit platforms

And why do you want zfs on an RPi?

Hi ryecoaaron ,

I used your automated one-liner to install OMV, which worked a treat. No errors to report. As for ZFS, its a filesystem I know well having worked with it for 5 years plus with OMV4 and Freenas/Truenas on Intel hardware. ZFS works surprisingly well under Ubuntu Server 21.04 on the Pi 4B 8GB with Portainer acting as my Docker GUI/Manager. However, I'd prefer to be running OMV5.x

I just think zfs on usb drives on an rpi is overkill but oh well. The problem with arm boards and the zfs plugin is getting the kernel headers installed so the zfs module can be compiled. The plugin can't list the headers for every arm kernel OMV can be installed on. So, you need to manually install them. After that, the plugin should be able to install ok. If you want to install the plugin after successfully installing zfs-dkms, that would probably help.

A little update, as this question is now solved. The solution was quite simple in the end, this is what I did.

Code

Linux pi8gbnas 5.10.63-v8+ #1459 SMP PREEMPT Wed Oct 6 16:42:49 BST 2021 aarch64 GNU/Linux

Code

sudo nano /etc/apt/sources.list

Add the line

Code

deb http://deb.debian.org/debian buster-backports main

Then

Code

sudo apt update

Then

Code

sudo apt install zfsutils-linux/buster-backports
sudo apt install zfs-zed/buster-backports
sudo apt install zfs-initramfs/buster-backports

The kernel recompile takes quite a while even on SSD attached USB.

Then you're ready to add the OMV ZFS extra, don't choose the armhf version. And bingo it should all be working, Pi4, ZFS, OMV deliciousness.

omv-extras has a checkbox to enable/disable backports. So, no need to add the backports list file manually.
