Plex Gpu acceleration

[Herbie4206]

Im trying to enable gpu acceleration in trunas but i keep getting an error.

Can someone tell what I am doing wrong?

I can post the error log if it helps.

When I was struggling with hardware transcoding in Plex, I came across a number of posts with that uuid error in various TrueNAS forums/threads. It wasn't relevant to my issue (I had no errors, it just didn't seem to work), but you might get lucky if you try to search for that error.

I seem to remember there were some suggestions of command lines to fix it.

Try THIS coming from the thread you can find HERE

I have no idea where to find the user_config.yaml file in either hexos or truenas i cant find the directory that was supposed to be automatically created when plex was installed. Would you know where i could find it?

Have you got Plex pass? Pretty sure you need Plex pass for this feature.

In truenas go into 'system > shell'

Run this

midclt call app.gpu_choices | jq

Take note of the output - you need the pci_slot value, this should look something like 0000:01:00.0 and you need the uuid value which should look something like GPU-ab0fdc2d-e1f7-d2fc-54e0-5b34ff44c3d9. You can copy from shell by highlighting the text and using CTRL + Insert

Then run the following replacing PCI_SLOT with your pci_slot value and GRU_UUID with your uuid value

sudo midclt call -job app.update plex '{"values": {"resources": {"gpus": {"use_all_gpus": false, "nvidia_gpu_selection": {"PCI_SLOT": {"use_gpu": true, "uuid": "GPU_UUID"}}}}}}'

This is the method I used and it worked like a charm

@Herbie4206 Have you upgraded to 24.10.2 via the truenas UI, that did fix the GPU loading for me.

doesn't updating trueNAS break HexOS though?

some users have reported it not breaking HexOS
the official stance of the HexOS team is that it is not a supported usecase and it may or may not break things.

When I updated truenas, hexos has kept working as it's supposed to.
