Hi, 4 out of the past 5 parity checks performed on my server showed sync errors, but no idea where they are coming from. (I've attached a screenshot and server diagnostics below.) Are there any elements which you'd recommend me checking to figure out where and why these sync errors are reoccurring? First I expected it to be a ram failure, but a memtest86 on all ram sticks individually gave me a pass with 0 errors. I also reseated all the drive cables incase some came partly unplugged, and I shrank the array by removing an older drive which had 3 reallocated sectors, but im still getting errors. I'm currently performing another parity check, but again the server keeps finding new errors. Thank you! fluxion-diagnostics-20230306-1029.zip

Problem solved! There seemed to have been an issue between the system bios and the nvidia drivers (im guessing). I updated the motherboard bios which was 2 years old, changed some bios settings and after a couple reboots unraid recognized the nvidia gpu again. I am able to access the nvidia driver plugin with no issues now.

Thanks for these tips. Did a parity sync first, completed successfully. Then took out the Nvidia P2000 gpu from the unraid server and gave it a good run through Furmark in another system. The gpu seems to be working as it should, no issues or crashed popped up. I put the gpu back in the server, after checking it is seater properly, yet again the unraid system becomes unresponsive the moment I try accessing anything gpu related (Nvidia drivers plugin or GPU stat plugin). It doesn't even let me shut down gracefully, have to force shutdown everytime which is making testing this multiple times over not a pleasant process. Anything else you'd recommend me trying out as a possible fix? Thanks a lot

Hi, after replacing a faulty harddrive with a new one in my unraid server, I am able to start up unraid, change the drive in the GUI, start the rebuild process, but then right after the rebuilding process has started, the Unraid GUI stalls and stops working completely. From the syslogs it appears that the Nvidia driver is causing the system to misbehave and become unresponsive. Here's the original post where I enquired about this issue: As reccomended in this previous post, I rebooted in safe mode. Tried installing Nvidia driver plugin again, but it behaves exactly the same over and over again. It says its installed properly, but then refuses to open the Nvidia drivers plugin page, then it freezes the GUI. After quitting my webbrowser, then logging back in into the server the GUI seems to work again, but the server is not reacting to the reboot or shutdown button anymore. Other services like the terminal don't work either. It forces me to hard shutdown the server everytime after trying to install the Nvidia drivers plugin to be able to access the server again. Any idea why the Nvidia driver plugin is breaking the server like this? And any idea of a possible fix to get it to work again? Ive attached the most recent syslogs to this post incase they might be of any use. Thanks for the help Fluxion_Syslog_08Feb2023.txt

Okay. Just rebooted in safe mode. Tried installing Nvidia driver plugin again, but it behaves exactly like previous two times. It says its installed properly, but refuses to open the plugin page, then it freezes the GUI. After quitting my webbrowser, then logging back in into the server the GUI seems to work again but the server is not reacting to the reboot or shutdown button anymore. Any idea why the Nvidia driver plugin is breaking the server like this? And any idea of a possible fix to get it to work again? Thanks

Okay, got it, thanks. I tried powerdown -r to shutdown the server via the console, but the server does not seem to react to it. Web GUI still unavailable. Is there another command line that could work or is a hard shutdown necessary? The server started rebuilding the 8TB swapped hard drive yesterday before I encountered all these issues, been going for about 22 hours now. Will this break the parity at all or will the data stay emulated if the rebuilding process is broken up? Thanks

I was able to SSH into my server via PuTTY so it seems to be still up and running. The command line you provided above did not do anything, so I entered the next command line in the console instead: cat /var/log/syslog I saved all the provided info from the console into a text file attached to this reply. Is this all the syslog info you need? Thanks for the help Fluxion_Syslog_08Feb2023.txt

Thanks JorgeB for the reply. Only issue here is when I replace a drive, I am able to start up unraid, change the drive in the GUI, start the rebuild process, but then right after the rebuilding process has started, the Unraid GUI stalls and stops working completely. I cannot access the Unraid GUI at all to download the diagnostics nor the syslogs. I just replaced another drive and lost complete control of my unraid server again. 3rd disk replacement in a row this is happening. I realize there is not much for you to assess without logs here, but have you heard of an issue like this before, or any idea what might cause this? Thanks a lot

Hi, over the past week I've replaced two drives in my array, and on both occasions after/during each drive replacement, some dockers (plex, tautulli, krusader) and gpu nvidia driver plugin with the gpu itself become unavailable. When trying to open any of these tabs during and after the disk rebuilding process, I get a blank white page and the unraid GIU becomes unresponsive, resulting in having to close my browser completely and having to log back in into unraid to be able to access the dashboard and main page again. Sometimes the Docker page loads but if it does, it takes numerous minutes to do so. Both replacement drives were pre cleared using the UD Preclear Plugin. Disabling and reenabling the docker tab does not result in a fix. After the rebuilding process, the server also does not react to a graceful reboot or shutdown. First disk I replaced was on Unraid V6.11.5, then I restored back to V6.11.3 for the second drive replacement since I thought that could have been the issue, but it wasn't since I'm again experiencing the same issues. Also when trying to download my server diagnostics, the download popup hangs on these last two lines: ls -lA /sys/class/drm/*/device/driver 2>/dev/null|todos >>'/fluxion-diagnostics-20230113-1107/system/drm.txt' /usr/bin/nvidia-smi --query 2>/dev/null|todos >>'/fluxion-diagnostics-20230113-1107/system/nvidia-smi.txt' Any idea what could cause these issues? I've replaced drives in the past but never experienced these issues before. Thanks,
