Getting ZFS Working

[mikeotoole]

Hello, I'm looking to get ZFS working. This is on a Raspberry Pi 4. I generally followed the instructions here for a fresh install.

Thanks for the help and thanks for getting Proxmox 8 working on the Pi!

Here is what I've tried.

I'm using real Debian images from https://raspi.debian.net/daily-images/

generally it's easier to use btrfs on raspberry in fact of memory amount.

have you added the "contrib" to /etc/apt/sources.list ?

Mine looks like:

deb http://deb.debian.org/debian bookworm main contrib non-free-firmware non-free
deb http://deb.debian.org/debian bookworm-updates main contrib non-free-firmware non-free
deb http://security.debian.org/debian-security bookworm-security contrib main non-free-firmware non-free

Backports are not enabled by default.

Enable them by uncommenting the following line:

deb http://deb.debian.org/debian bookworm-backports main non-free-firmware

I don’t know where to download the header either. You can compile the kernel yourself or install a generic kernel with zfs integration.

#kernel repo.
deb https://global.mirrors.apqa.cn/proxmox/debian/kernel sid port

do

apt update && apt search pve-kernel-6.1*
apt install pve-kernel-6.1.X-generic pve-headers-xxxxxxxxxxxxx

To get kernel header, check the .deb download URL here: jiangcuo/Proxmox-Port#2 (comment)

Thanks everyone for the options and details! I ended up doing the following and got it working.

sudo apt install dpkg-dev linux-image-arm64

wget http://archive.raspberrypi.org/debian/pool/main/r/raspberrypi-firmware/raspberrypi-kernel-headers_1.20230405-1_arm64.deb

sudo dpkg -i --force-all raspberrypi-kernel-headers_1.20230405-1_arm64.deb

sudo apt install zfs-dkms zfsutils-linux

sudo modprobe zfs
