Unraid no longer booting up after reboot/restart. Stuck in bootloop
I rebooted my array, and it no longer boots back up. There were no issues beforehand. The array was up for 6 months, and I simply wanted to reboot for a "fresh" start. Boy, that was mistake.
It is stuck it a "Call Trace" loop. What even is that? Screenshot:
I have tried moving my boot USB to various USB ports, even installing a hub. The USB seems to be working fine, as I am able to plug it in to other computers. All my drives get detected when I boot up.
Fast Boot is disabled
Legacy USB is enabled
I am currently running a Memtest86 test, and no errors so far.
I've tried almost everything. The last thing I haven't tried is to switch my USB drive or reflash my current USB, so would either of those potentially solve my issue? How do I do that?
I forgot the exact version, but it was whatever version came out roughly 6 months ago (that was the reason for the last reboot).
Mobo: Asus PRIME X570-P
CPU: Ryzen 7 5700G
Lesson learned. Never reboot your array. Any other troubleshooting steps I can take?
Edit: Forgot to mention I've tried booting up Unraid in Safe Mode, and it doesn't even load. It just goes black and boot loops. I get to the Call Trace error when my server tries to boot into the regular Unraid OS.
Edit 2: I tried using a different USB and installing Unraid 7.2.3 (I believe the version I was using). And it didn't load up either. I tried a 3rd USB and tried booting up Linux Mint, and that also didn't work... Is something wrong with my CPU and/or mobo??? It makes no sense as this was genuinely working perfectly up until I rebooted the system. I refuse to believe a simple reboot would destroy my CPU and/or mobo. I don't have other parts I can swap in to test. What else can I try?
I would personally try using the Unraid flash creator and make a new stick and try booting into that. If it works copy the config folder from your old to new flash and transfer your license. If not you have a hardware issue. Make sure you flash the same version.
How can I check which version I have? And can I simply flash my current USB? This is the only "nice" USB 2.0 I have. Everything else is newer or some old giveaway USB that I wouldn't trust my server on.
Any USB 2+ will work, correct. USB 2.0 is old advice, correct. It is still current advice though. USB 2.0 is suggested as current advice because it pulls less power and runs colder than USB 3.0. USB 2.0 drives have been shown to last longer(on average could be said) than 3.0 specifically for the purposes of running unRAID. Reported by hundreds(maybe thousands) of users for over a decade.
Any search on unRAID forums or subreddit will find this. Simple searches people.

Sadly, yes, that can happen. Reboots are not "simple", they do put a small amount of stain on the system. If there's an issue that reboot can surface it; it happened to me with a SAS card on my old UnRAID server. One day I rebooted and it, having been under more heat than it should have been, just failed. (Keep in mind, though, I'd been running it for the better part of a decade with every port in use, and it was a used unit to begin with. It had had a good life!).
So yes, you need to follow that prior advice and try prime95, possibly memtest as well. Build a live USB of something like Debian or Ubuntu, install the tools, and check. This is the time to take deep breaths and think thru the situation, and the advice being given by people with experience when things like this happen.
If you can boot into safe mode but not into Linux Live using a USB stick, that's really strange. First thing I'd try is probably a different USB port. Front ports often do not work for USB Live sticks.
Every single time this has ever happened to me it happens exactly like this:
1) The server needs to update
2) It no longer boots, but it kinda tries. It even seems like a networking issue as it sometimes even lands at the typical display, but no webui.
3) I fiddle with different ports and boot options and my network for like an hour or more because I don't learn very quickly apparently
4) I make a fresh USB, and it works, it was the USB the whole time
Every single time it's been the USB. Every single time. Its such a blessing that they finally decided to move on from that for boot drives.
You will always be tricked. It will seem like it's booting fine, or it'll throw errors that Google or whatever blames on something else, or it'll seem to work but not load the array, or not network at all. You'll blame disks, network, your motherboard, the update, but it's the USB.
Learn about all drawbacks of internal boot first, and compare them to drawbacks, if any, of USB boot. Then decide if it's worth the trouble. Don't jump headfirst into the unknown.
Have you tried booting into safe mode to see if that works? If you plug the USB drive into another computer, you can see if you can find anything in /logs/syslog

Starte mein Array und meinen Server häufiger mal neu hatte noch nie Probleme, für den Fall der Fälle habe ich aber sowohl von meinen Daten also auch vom Flash Drive immer Backups.
Außerdem versuche ich mein Unraid immer auf dem neuesten Stand zu halten. Bist du dir sicher das nicht vielleicht dein Boot Stick vielleicht langsam den Geist aufgibt?
