ZFS Support

[joshdick]

tl;dr: It seems like ubuntu-rockchip's kernel customizations are incompatible with the ZFS kernel module; is there any possibility that compatibility could be added? Or is there already some other known way to get ZFS working?

Thanks for all of the work you do on ubuntu-rockchip!

I am attempting to use ZFS on an OrangePi 5 running the v1.27 ubuntu-22.04.3-preinstalled-server-arm64-orangepi-5.img.xz image.

Attempting to sudo apt install zfsutils-linux results in:
