Every time I shutdown and restart my server, or just reboot, UNRAID does not come back up. During the boot process it always stops at the same place.

The link at the bottom of this post is from my original report on this and the solution, at least till the next reboot. It's now happened a total of three times with three different USB drives. The two most recent USB drives are PNY, I'm not sure what the first was. I've tried plugging the drive into different USB ports but this has not helped. This started on version 6.12.14 but also happened on 6.12.15 and 7.1.4. The system always stops at the same place shown in the image below. I need some assistance figuring out what is causing this and how I can fix it for good.

Can you boot/reboot multiple times with a stock install?

I've tried this with 7.1.4 and I can reboot one time. On the second reboot, even if nothing is done, it stops at the same place.

I've done this twice now and got the same result both times.

Make sure Fast Boot is not enabled in your BIOS settings.

I'm a bit skeptical that this is caused by a switch in BIOS since it's been running fine with no BIOS changes for years. That being said I'm happy to check the Fastboot in BIOS when I get back home but on my SuperMicro motherboard it looks like this feature is called Quickboot.

Thank you for the suggestion.

The quick boot option is disabled

Now it stops in the same place even with a freshly built new USB drive (7.1.4)

I may have been a bit premature with this post. While this was a freshly built new USB drive I did, mistakenly, copy over my license file from the old drive (config/Pro.key). I say mistakenly becuase this license file was for a different USB drive.

I tried this again without copying over the license file and it started up just fine. There was no license so the array would not start but at least UNRAID was running. I didn't do anything on the system and just rebooted. It came back up just fine. I rebooted at least half a dozen times and each time it came back up fine. At this point I decided to request a trial key via the UI. It was downloaded and installed just fine. Then I rebooted again and now it stopped at the same place as all the other times.

I realized that as I've been working on this every time there was failure I either copied the entire config folder over to the USB drive or I copied nothing over and added the license via link in the UI and it was after this where the system would no longer boot up. I'm not sure if this is related to the license file itself, any file being added to the USB drive, or just a big coincidence.

Any ideas on what I can do next?

So just copying the wrong key to a stock flash drive makes it stop? That doesn't make sense to me.

I rebuilt the same USB as in the previous try. Did not copy any files over to it and did not install any license file. I've been able to add multiple apps, users, and change settings all with multiple reboots and no problems.

Or even a correct trial key makes it stop too.

I rebuilt the same USB as in the previous try. Did not copy any files over to it and did not install any license file. I've been able to add multiple apps, users, and change settings all with multiple reboots (at least 10) and no problems. There was not much left to do without adding drives so I recovered the trial key via the UI (not directly copying the file to the USB drive). I rebooted, which did work (once) and then I added my drives and started the array. I rebooted again and this time it stopped in the same place.

it should be noted that I'm using UNRADI USB Creator V1.0.1 on a Mac and I am running the make_bootable_mac script once complete and cleanly ejecting the USB drive when done.

This is a very strange issue, but I still have some doubts the key is the problem.

I would agree but it seems to be the only common change when the system goes from working to not. I'm not really sure where to go from here. I think I can get the system up and running and start the array but I whenever I reboot this problem will resurface. Obviously not good but I don't know what else to do.

Try booting the same flash drive in a different PC, if available, and see if it does the same

I tried the trial dive that was not working in my server on two different desktop machines. It worked on both even with multiple reboots.

This would seem to indicate that I have a problem with my server, no? I'm guessing either BIOS or motherboard or perhaps RAM / CPU? I know the BIOS is the latest version (if one can call 2012 latest) and it has not been edited in years. Is it possible that the settings just changed on its own? Any good way to track down what the culprit might be, or with the age of the MB (Supermicro C2SEA) would I be best off to just replace it? My concern here is that this very likely means replacing almost everything since the CPU and RAM won't fit in newer MB sockets and even the drive adapters (two Supermicro AOC-SASLP-MV8) may not fit in the slots available on newer MB.

That would be my guess.

Replaced the motherboard, CPU, and RAM. No more problems.
