I recently purchased some hardware (used) to setup an unRAID server to start learning on before I moved Plex and other services over to it.

I've installed some dockers, messed around with nginx and a few others just to get familiar with how they work within unRAID. After playing around for a few days and feeling a bit more comfortable messing with things, I formatted everything and started from scratch, then threw the rest of my drives in the array so I could start migrating my Plex library

The issues

Over the last week, at least 3 mornings I woke up at 6:45 and found that the server was not accessible over the network. I go into the office and find a bunch of stuff on screen and it's completely non responsive via keyboard. It can run ALL day long, but somewhere between 1 AM - 4 AM is just shits itself.
Everything I purchased was used, so there is a possibility of a hardware issue, but I really don't know where to start. Logs won't seem to help as they're lost on reboot and I can't pull them via terminal when this happens because, like I said, the system is unresponsive. I'm new, so there may be another way to monitor this that I'm unaware of; please let me know..

 

My nginx docker breaks after every reboot. Clean or not. The only way to fix it is:
a. backup /appdata/nginx
b. uninstall nginx docker via CA
c. delete /appdata/nginx
d. install nginx docker via CA
e. restore /appdata/nginx

 

My custom image in the server description area doesn't persist through a reboot. It just shows a broken image icon until I reupload. Is there a place I should keep it on the machine itself, or shouldn't uploading it place it somewhere automatically?

 

 

Troubleshooting
1. Memtest for 24 hours, 0 errors
2. Pulled flash drive and performed a "Scan and Repair" on my Windows desktop
3. Formatted and reinstalled unRAID version 6.7.2 on the flash drive, formatted all drives for a fresh start.

4. Replaced Flash drive with a Fit 16Gb and completely reinstalled again.

5. Currently running mostly vanilla with only CA, Dyanmix SSD Trim, rclone, Nerdpack, Dynamix Temp Mon installed.  No dockers or VMs at the moment.  So far, so good for the last 10 hours, but the issue always happens early in the AM.

6. All hardware was purchased together, so I know the CPU and board work together and the BIOS is on 3.2, which I think is the last update before the Spectre fixes.

While the system is working, go to Tools - Diagnostics and attach the complete diagnostics zip file to your next post. You can save syslogs by using the Syslog Server feature.

I have syslogs up until it crashes both yesterday and the day before, along with screenshots of the monitor when it becomes unresponsive.  

  

Since the clean install yesterday morning on the new flash drive, I'm up and so far it's still running.   I'll keep monitoring though.   Attached diag file.

You don't need 50G for your docker image. I usually recommend 20G and it is very unlikely you would ever use even that much unless you have a docker application misconfigured. And making it larger won't fix that problem, it will just make it take longer to fill. Your docker image shouldn't really grow.

 

Doesn't look like you are running any dockers yet so a good time to decrease it.

When is your mover set to run?

When is your mover set to run?

 It's set for 03:30.

 

 

Also, since the new flash drive and clean install of unRAID, it's been up and stable for nearly 48 hours.
