Creating a ZFS zroot Raid 10 on Ubuntu 16.04

Ubuntu 16.04 Xenial Xerus is finally out with full ZFS support. So I embarked on a journey to get a fileserver up and running with the goal to:

  • Boot from ZFS
  • Have a Raid 10
  • (Raid 10 is not a requirement for this tutorial to work)

tl;dr

  • Use the Ubuntu Desktop DVD for the installation
  • ZFS UEFI installation does not work in VirtualBox
  • Putting the boot partition inside a zpool does not work. Use a separate UEFI partition for /boot
  • Grub2 has to be installed after the first time you booted your newly installed system
  • Follow this tutorial
