Increase ZFS Allocation

I can’t figure out how to increase allocation of my ZFS Pool. Here are my zpool and zfs list outputs:

I have tried increasing the partition size, but It is currently at the maximum. I have only been using Proxmox for around a year, and the ZFS functions are still confusing to me. Any help is appreciated. Thanks.

I am not sure if I understand what you are trying to accomplish. Are you trying to have one pool and increase its capacity? it seems like you created two ZFS pools in the screenshot. I apologize if my answer seems more like a question, but I am trying to understand what your goal is.

Sincerely,
