why

I wanted my new proxmox to have mirrored boot drives for redundancy resons. I used somewhat large drives, meaning to pass them trough to a TrueNAS instance

how

Basically just install debian on a mirrored root zfs and then put proxmox on top

• put 2 drives into the system
• follow the Root on ZFS Guide by OpenZFS and set the drives up as a mirror.
• follow the Install Proxmox VE on Debian Bookworm Guide by Proxmox. As new Debian versions are released, new guides will probably be published but the basics likely remain the same
