I recently acquired some server class hardware AMD EPYC 7532 and ASRock ROMED8-2T I went through the bios and turned on virtualization and IOMMU installed Proxmox just like i have on my current other build and passed through the HBA cards and a M2000 i had laying around and a P4000 that work was going to toss. I then installed Truenas scale 25.04. Went to Apps → Configuration → Settings and checked the Install Nvidia Drivers box then saved. I gave it a minute and restarted. When i went to test install an App just to make sure the video cards would show up in the app and neither card is there. When I go to nvidia-smi I can see both cards and they do not have any processes. If i sudo nvidia-smi -i -pm ENABLED to each card i can now see them in the app but i get a UUID error when i go to try and start the app. So i shut that Truenas verson down and loaded 23.10 because i know that had the Nvidia drives baked in. Attached all the same pcie devices as before and boom the GPU’s show up and work properly. What am i doing wrong with the new version that im not with the old version.
Finally had time to test just straight installing Truenas Scale 25.04 onto the 2 NVME drives and everything is working fine seams like the issue is with the way Proxmox is trying to pass through the GPU’s
