boot zfs raid1 from partitions

[proximity]

What is the correct way to install proxmox so it installs and boots from 2 partitions on 2 drives (zfs)

So the idea is to have it mirrored on partitions on 2 drives and use the remaining space on the drives as non mirrored storage for virtual machines.

You could try the normal ProxmoxVE ISO installation and just install it as a ZFS mirror. There are advanced ZFS options where you can use "hdsize" to tell the installer to only use a specific amount of storage so you got empty space to add your own partitions later.
