[solved] - Issues with Installing Plex App on TrueNAS Scale with UHD 630 GPU passthrough

[h0st]

I recently encountered an issue with installing Plex on a freshly installed TrueNAS SCALE system with UHD 630 graphics. When I tried to install Plex with the application GPU support setting enabled, the installation failed with the following error:
Required value: Limit must be set for non overcommitable resources

Code:

Code:

middlewared.service_exception.CallError: [EFAULT] Failed to install chart release: Error: INSTALLATION FAILED: Deployment.apps "plex" is invalid: spec.template.spec.containers[0].resources.limits: Required value: Limit must be set for non overcommitable resources

I attempted to resolve the issue by disabling the GPU sharing option, installing Plex, stopping it, and then enabling the GPU settings and starting Plex. Unfortunately, this did not resolve the issue as Plex still failed to detect the GPU. Additionally, when I tried to change any settings and save them, the same error message persisted.


After some trial and error, I managed to run another version of Plex using the docker CLI and the lscr.io/linuxserver/plex image with /dev/dri sharing with the container. I was able to confirm that igpu was recognized by Truenas, and the Transcode function worked correctly. However, managing it was still a bit of a pain.

Has anyone else encountered this issue and found a solution? I'd love to hear any suggestions on how to get a running Plex app via the GUI without any issues with the GPU sharing setting.

Thanks in advance


edit :
The update .41 of the plex chart fixed the issue

I have the same issue. If I leave everything with default settings, I am able to install but the application cannot be deployed.
Also tried to disable GPU and Enable Host Path Safety Checks but with no luck.

Yes, I think it's related to TrueNAS Scale not allowing any other application to use the GPU.

As I mentioned earlier, it seems that there's a bug with TrueNAS that prevents any other app from using the GPU. Which probably a bug in it coz, I was able to run a Plex server with hardware transcoding from the CLI using the following command:

Code:

docker run -d \
  --name=plex \
  --network=host \
  -e PUID=1001 \
  -e PGID=100 \
  -e VERSION=docker \
  -e PLEX_CLAIM=claim-YOUR-TOKEN \
  -v /YOURPATH/plex/config:/config \
  -v /YOURPATH/plex/series:/series \
  -v /YOURPATH/plex/movies:/movies \
  -v /YOURPATH/plex/anime:/anime \
  -v /YOURPATH/plex/others:/others \
  --device /dev/dri \
  --restart unless-stopped \
  lscr.io/linuxserver/plex:latest

Just make sure to run the command ls /dev/dri and check if you find renderD128. If you're using a VM with GPU passthrough, you'll get renderD128 and renderD129.
