Hi All, I’ve had Truenas running nicely in a VM on Proxmox for several days. The current pool is RaidZ1 using nvme disks I Now I want to add USB storage to a new pool, but I’m getting a Topology error: “Disks have duplicate serial numbers: None (sdb, sdf)”

The USB disk is listed as unassigned when I try to create the new pool, and has the correct info.

In Proxmox I can see bus and ID info using lsusb, but there’s nothing under /dev/disk. So I don’t have any path info to use with qm set. I’ve tried adding storage with a couple different USB drives but get the same serial # error.

Am I missing something obvious?
