Hi All,
I’m wracking by brains trying to work out how I can get my NVIDIA GTX 1660 working with Plex (transcoding) and Immich (machine learning). I recently upgraded from TrueNAS-Core to Scale (Dragonfish).
I can confrim that Plex is not using my GPU for encoding, as my CPU usage spikes considerably when it’s transcoding, and there are no processes present in when I run nvidia-smi while transcoding.
When I run the maching learning pods in Immich i get continual ERROR Worker was sent code 139 which is a SIGSEGV memory violation error.
I think the issue is that my GPU is being used by something and is not available to the system, as [VGA Controller] is listed after the GPU when I run lspci – if I understand the meaning of that correctly.
TrueNAS Scale Version: ElectricEel-24.10.0
Plex Version: 1.0.24
Immich Version: 1.6.24
I do not have any displays connected.
I have followed this post which details adding the following code…
resources:
gpus:
nvidia_gpu_selection:
'0000:07:00.0':
use_gpu: true
uuid: '' <<-- the problem
use_all_gpus: false
… to the user_config.yaml file, located in the ixVolume volume, found at /mnt/.ix-apps/user_config.yaml, and setting the IOMMU and UUID values correcty – which I have done.
I also came across this post. However, I’m able to run the nvidia-smi command without errors.
Interestingly, I don’t have any of the following files on my system:
/etc/modprobe.d/kvm.conf
/etc/modprobe.d/nvidia.conf
/etc/modprobe.d/vfio.conf
My system also doesn’t present me with any GPUs avaible for isolation, as shown in the screenshot further below.
Is anyone able to point me in the right direction as to what I should do?
