unRaid Nvidia bug after update to 7.2.5

[Neminem 1729]

Calling out to all unRaiders.

When you update to unRaid 7.2.5 you might have issues with Nvidia support in your docker containers.

Read this https://forums.unraid.net/topic/198521-unraid-os-version-725-available/#findComment-1620492 to fix it.

I'm still not sure if this fix will persist a shutdown or reboot of unRaid.

Here is a quick how to.

unRaid 7.2.5 Nvidia Bug 

Might needs to be done after Reboot and after shutdown.
I really like my UPS right now  

Stop Docker
Open terminal copy / paste the following lines into terminal.
1 line at a time.

nvidia-ctk cdi generate --output=/etc/cdi/nvidia.yaml

nvidia-ctk runtime configure --runtime=docker --cdi.enabled

Start Docker

Isn't it just that the driver has been updated and that 10 series and below cards are no longer supported on the the newer drivers?

If so choosing a lower version in the plugin should fix it.

No it was not that simple.

I was on the last driver version that was supportet / recommended.

Hence the quick fix, was to do the following, and that would not be persistent.

What the updated plugin did was to automatic do the above and persistently apply on reboot / shutdown and reapply after driver update.

The funny thing is that it only afflicted docker containers, and docker was updated to 29.

Okay, thought it was just the problem that happened last time the nvidia plugin updated.

Thanks for the information!

If you're using UNRAID with Nvidia you should really be using a Quadro to begin with. Even if it's just for transcoding the bus powered cards can still do a fair amount of transcodes without breaking a sweat. Even a potato P1000 can handle up to 14 streams but needs hacked drivers due to the 8 session limit.

My server is just using old parts from the main computer, so i will never have something like quadro cards to put in it.

You can get them for about $60 on ebay..Will make your life so much easier to boot.

Those cards will not work for me, they only have 4GB ram.

I use my 1080 8GB for some light AI fun, OCR and / or subtitle translation.

I you my iGPU with Emby

Tbh i see no reason to spend money on a quadro card when the old card i have does the job.  

Besides, i'm in the process of moving my Emby server to another small computer with a Intel CPU that can handle the transcodes as well.
Doing this so i can do some heavy stuff on the main server without affecting Emby and freeing PCI lanes for a HBA card.

If its for unRaid, remember to get your HBA flashed as IT mode.

Other wise you can't use it with your array.

Yeah, learned that the hard way a couple of years ago
