Gaming Windows VM. So it's really a fix from drivers

Sorry, but this has nothing to do with the Nvidia Driver since if you are using it in a VM it is actually discouraged to install the Nvidia Driver Plugin (also see the first page).

I just feedback based on my usage here. I'm using 3070 for several years and I didn't have problem using it that way (no passthrough via VM) until I upgraded to 5000 series I experienced these problems. I tried the same troubleshooting and those errors don't appear in logs anymore. It's just my observation 😁 I want to use it on both unraid and gaming VM, I don't want to passthrough. Glad this problem is fixed now hehe

Hello, hoping someone can help.

I upgraded my server from 6.12.13 to 7.2.3 last night. During the update I got some messages about the NVIDIA plugin I use for transcoding with my MSI GTX 1050 Ti. I followed the instructions, but after reboot I started getting errors from the plugin.

First error right after reboot:

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

After that I’m now consistently seeing this:

Failed to initialize NVML: Driver/library version mismatch

NVML library version: 590.48

It looks like parts of the driver are on different versions and they’re not playing nice.

Here’s what I’ve tried so far:

• Switched between Latest, Production, and several of the Available Versions in the NVIDIA plugin.

• Rebooted after each driver change.

• Tried installing a single driver version, rebooting, then trying a different one.

• Confirmed the GTX 1050 Ti shows up under System Devices.

• Uninstalled the NVIDIA plugin, rebooted, reinstalled it, and rebooted again.

No matter what I do I still end up with the Driver/library version mismatch error when I check the plugin under Installed GPUs.

At this point I’m thinking something from the old driver is still hanging around after the OS upgrade, but I’m not sure how to fully clear it out without messing something else up.

Any ideas on how to properly clean this up and get the driver versions back in sync?

Thanks!

Oddly enough I had the server running for a little while (5 or so hours) with the production option chosen and I randomly got a notification that version v580.126.09 was found and downloaded and that I'd have to restart my server.

I did that and now my GPU is recognized properly in the plugin. Not sure what the deal was but I'm happy it's fixed. I really hope I don't have to deal with this when I replace this GPU in a few weeks after an upgrade I have planned.

Recently I installed an old Nvidia 1080 graphics card, and the system became unstable. So unstable that it started either hanging completely or rebooting multiple times per day. Everything pointed to the problem being with the NVIDIA drivers, including the monitoring app consuming 100% of at least one CPU. I could only tell when I could login to the actual machine, which I don't have it really setup for, unfortunately.

I removed the NVIDIA driver, and disabled (for now) the one app that used it, and my system has been stable for the past 15 hours, so without a lot of data to back that up, I'm fairly convinced it's something to do with the NVIDIA driver support.

I've attached a troubleshooting dump, if anyone has the time to take a peak.

Thanks.

Most of the times it is simply enough to Uninstall the GPU Statistics plugin or set the query interval to something reasonable like 5000ms or even 10000ms.

Please go also yourself through your syslog, it seems you have a massive issue with the UPS plugin too.

I recently installed a 5070 card and moved over to the Open Source version of the driver and NVIDIA-SMI can't find the card. Any other suggestions?

Any suggestions? I've deleted any old remnants of previous driver//app installs. Card is an RTX3090 and not isolated via VFIO.

I highly doubt this, but other then downgrading my Unraid OS, is there anyway to use the previous drivers? I have a Nvidia GT 730 and it uses linux driver version 470.256.02.

I remember seeing it somewhere i may have to setup up the driver file to use that version and kernel that unraid is currently using. If that's the case, is there a tutorial to follow? I have never done that before.

May I ask for what do you use the card actually?

And yes, currently the old legacy driver doesn't compile against recent Kernels which all currently available Unraid versions are using.

However there is a patch out there for the old legacy driver to make them work again, however I already tested that and I'm pretty certain you don't want to crash your server often correct? These patches make the driver work but the server becomes completely unstable.

Sorry but the blame goes to Nvidia since they now deprecated these cards.

I have a Nvidia GT 730 in my server right now. Been trying to find a relatively cheap that is more up to date for transcoding.

If you are searching something cheap then please look maybe for a Nvidia T400/T600/T1000, you could also get away with a Intel Arc Card even an A380 will do the job just fine and the A380 is also capable of transcoding AV1, as long as the software you are using is capable of transcoding AV1, with the benefit of not having to install a driver.
However the idle power draw is a bit higher in idle with the Intel card from what I know.

The transcoding is basically done through Plex. I was also thinking of using the GPU to create subtitles through Whisper.

I tried setting up transcoding videos "manually" to save space on my media server, but got frustrated trying to find the best settings to use that save space and still be usable on plex.

Used T400 are available on eBay for as low as $50USD.

I recently bought a new A400 for $180, delivered. Replaced a P400. Figure I'm good for several years now.

There really isn't anything a GT730 can be used for anymore. Even Win10 required a GT740 as the minimum GPU it would support.

I compile the Open Source drivers when a new Unraid version is released.

So to speak, when the next Unraid version is released you should see the Open Source 590.x series driver.

Any way we can install an older version of the Open Source drivers?

I'm trying to use an RTX 5060 ti (which requires the OpenSource driver) with a GTX 1660 Super, splitting the GPUs between different containers, but with the current Open Source driver, the 1660 doesn't support the Compute module, whereas with the prodction driver, the 5060 isn't even supported.

Downgrading the driver might solve the 1660 issue (see here), but I need to downgrade to another Open Source version.

Thanks

But in general no.

Sorry, but I don't think that this is the culprit from the issue and why should the new driver shouldn't support compute?

Can you please first show your docker run commands for the containers? With which containers do you you have trouble?

Hey, I am very new to this and I am trying to set up a plex server and want to use my old GTX 1070 to transcode. I have the GPU installed in the server and installed the Nvidia driver app but it wont recognize my GPU. Any advice on how I can fix this issue?

This is the error I get:

Installed GPU(s):

Failed to initialize NVML: No supported GPUs were found

Unable to determine the number of GPUs

I just updated to unraid 7.2.4 and I'm not able to install the nvidia drivers. It runs, seems to install fine, but it doesn't seem to stick.

Essentially, ollama, plex, and a few other containers aren't running. I think it's because the nvidia driver isn't there.

Yes, exactly.

However I need always your Diagnostics, I can't tell what's going on on your system without them.

It seems you ran out of space on your boot device:

/dev/sda1 1.9G 1.7G 233M 88% /boot

From what I see your USB Boot device is only about 2GB, please consider a new USB Boot device if possible.

The driver needs between 300 and 450MB of free space on your Boot Device and 233MB is simply too less. If you want to fix that, you can delete the folder /boot/previous which contains the last Unraid version which most likely is exactly what you need.

I expected the nvidia driver would live in the cache drive. The 2gb USB has been getting more and more difficult to use but I need to look into how to swap from my decade old license paired with the drive sn.

Nope, that's not how it works and that wouldn't work because when the driver is installed (really early in boot) your cache driver is not even close from being mounted.

Transfering licenses is really easy, buy a new USB Flash devices (something reliable, I always recommend Transcend 32GB USB 2.0 Flash devices - please don't buy a USB 3.0 or even 3.1), Format it as FAT32, give it the Label: UNRAID, COPY everything from your old flash device to your new device (with that you still have your old flash devices if something goes wrong), execute make_bootable.bat as Administrator, boot from your new flash device, Unraid will say that there is an issue with your license on the top right corner, go to Tools -> Registration, there you should be able to transfer the license, after that you can start the Array, or even better download the Nvidia driver and reboot to be safe that everything is working.

Thanks for that, I'm going to try to update now. It makes sense that the nvidia driver needs to load sooner than the cache drives.

When copying to the new drive, could I just use a backup?

Plex still isn't starting. I'm not sure that's related.
