TrueNAS install on Proxmox with NVMe drives passthrough

Hello,
maybe anyone could just let me know if this project is either very uncommon or very unproblematic (or both). :wink:

Or does anyone have a clue how I would check that the PCIe devices/drives are unavailable to the PVE host after adding them as passthrough device? I guess they would just disappear from the list (lspci … ).

I thought I wouldn’t be the first one with a setup like that.

Thanks!
