Running Proxmox Backup Server inside Proxmox. For some reason, I decided to pass the controller to the vm, so PBS manages the pool.

I have 7x drives in a z2 pool. I want to add one more drive as a hot spare, but can't figure out how to do it. I found a console command, but proxmox throws a fit about the "add" switch (see below). I do not see a way to add one via gui, and I can't find any references in any P+roxmox documentation.

Code:
$"zfs add pool spare device" 

....unrecognized command 'add'....

$zfs --version

zfs-2.1.12-pve1
zfs-kmod-2.1.12-pve1
Seems kind of odd to me that one can't add a spare; am I the one screwing up?
