Last night my server unexpectedly shut down shortly after 1am - no issues with the UPS and everythng else was running fine. I powered it up but after a short while it shut off again. I did grab a diag dump before that happened, though I asume it will be missing any relevant info from the over night crash. It now seems to be powering off every time - the UI is useable but after a few minutes or so it powers off. I do also ship SNMP events to a remote server though, so I've also attached logs from just before the point where it originally shut down.

 

Any help is much appreciated.

Assuming this wasn't initiated by you, something or someone initiated a shutdown, this can be a plugin/scrip or a bad power button, trey booting in safe mode, if it still does it, unplug the power button from the board.

Note that you have a version of the Mover Tuning plugin that is incompatible with Unraid 7.  It is unlikely that this is causing your problem, but you should rectify this and move to a version that is compatible (assuming you still want that plugin) with Unraid 7.

The log would say if it was initiated by the power button, and it's doing a reboot so I'd say it's a script

The server initially powered down shortly after 1am. I turned it back on manually, but then initiated a standard reboot. So that reboot was likely from me.

Thanks. I don't actually run an array - I'm just using Unraid for Docker. I'll remove that plug-in though, once I get things back up and stable.

I was wondering why it completely shutdown after a reboot request, so that makes more sense

Yeah sorry for not being fully clear. I'm just running a check on 1 of the 2 drives in the cache pool. Once that's done I'll power up in safe mode and see what it does.

OK, so I had the server running for about an hour with no issues. I removed the out of date mover plug-in, checked nothing unexpected in the logs and fired up Docker. I'd moved it so I could connect a monitor and keyboard, so once I was happy that everything seemed fine, I moved it back to my equipment cupboard. After about 15 minutes it powered off again. No beep to indicate it was going to shut down, and when I check the remote syslog I see it was in the middle of bringing up containers, with nothing indicating any shut doen had been initiated. I just looked over and realised the power light was off.

 

I'm now noticing that my UPS is clicking about once per minute. However its not beeping to indicate its on battery, and none of the other equipment is having any issues. Its on Low sensitivity for input voltage. So overall I'd be a bit surprised if that was causing the server to completely power off, but its clearly possible that its related. I guess my next step will be to leave it where it is, but run a separate power cable to it, bypassing the UPS.

 

Anything else I should be doing in Unraid?

OK - so I powered the server back on after the above outage, but I then started seeing Emergency logs from nginx, indicating "Address already in use". I issued a reboot over SSH and its now come back up without those same issues - I've attached the logs from when it came up following the loss of power. Maybe its a result of the sudden power failure, and not part of the root cause?

 

Anyway the server is up again, this time running from a standard output (rather than the UPS). I'll see if it stays up for longer than 15 minutes...

This is almost certainly a hardware issue, PSU would be a good place to start.

Its now been running for about 17 hours without issues - plugged in at the wall rather than to a smart plug and UPS. I'll probably try moving it back to the UPS to see if the issue comes back, as if so I think that's then conclusive.

Either way this doesn't seem to be Unraid related, so I'll close this out. Thanks for the support, as ever!
