Hi, 

 

My unraid (v6.7.2) server, which has been running well until the other day, it completely stopped responding. I attempted to reboot it and it would sometimes get stuck on the "loading bzroot" stage. Other times it would seeming throw an exception. I have no idea what the green blocks on the monitor are:

 

 

I've tried a couple of things:

 

• Ran memtest, passed
• Copied a known backup flash copy from a month ago that I know works (v6.7.2)
• I'm using an old MobileLite G2, I replaced the card with a new Sandisk Extreme PLUS 32GB SDHC
• Replaced the MobileLite with a Sandisk Cruzer Glide 32GB
• Tried downloading and 6.8.2 clean format, copying my config from my known "good" copy
• Tried downloading and 6.8.2 clean format, copying my config from my known "good" copy, only selective files/folders:
• 

 

 

Sometimes it will actually boot to the login screen, but it soon throws some kind of exception.

 

Since the entire OS becomes unresponsive, how would I track down the log of this? I need to get a diagnostic, but IIRC unraid stores logs in memory, which doesn't help me here.

 

Next I might just try a completely fresh 6.8.2 install, but I don't want to have to recreate all of my settings from scratch... (Edit: just did this and it still faulted out -- seemingly there is a hardware error somewhere, but how can I figure out what's wrong)?

 

Any thoughts?

That's the most likely reason, but difficult to diagnose remotely, if you can start swapping some parts, like RAM, PSU, board, etc.

So I ended up completely reseating my memory and CPU (and reapplied thermal paste) -- everything looks good so far.
