urbackup

I'm trying out Proxmox for the first time and am having trouble understanding how to add an internal hard drive to a container. Here is my setup, detailed as best as I understand it: Computer is an old Dell Studio desktop with two drives: an SSD and an 8TB HDD. The node I setup is on the SSD...

So i'm trying to do something unconventional on older hardware. Ill explain where i am and what doesnt work and see if anyone can help me. I setup ZFS under proxmox and passed it via a mount to an LXC container. I have that working great and Urbackup is backing up into this setup no problem...
