Unraid crashing each night [6.8.2]


Recommended Posts

Unraid Verserion: 6.8.2

Recent Changes:

  • Upgraded a 1TB HD to 4TB HD WDC_WD40EFRX-68N32N0_WD-WCC7K3LF2DJD - 4 TB (sdi)
  • Upgraded to 6.8.2

 

After these changes I'm experiencing nightly crashes.

Troubleshooting:

  • Ran memtest from Unraid bootup option for 3 days with 15 successful passes.
  • While a parity check is running over night unraid does NOT crash.  This leads me to believe maybe MOVER is crashing the server but not sure how to troubleshoot that.   Today I plan on trying to disable MOVER.

I have the syslog mirrored to the flash drive already, but it doesn't really show anything.. Just shows HD's being spindown and then when I have to hard-restart then unraid starts writing to the syslog again.

 

Crash again last night on 6.8.1 so the problem isn't with 6.8.2.

Problem seems to be with one of the docker containers.  (wonder why safe mode doesn't disable docker containers).

Server up for past 2 days, I'll start going through each docker now.

 

It maybe due to the "New Permissions" which I ran recently and maybe broke or caused problems with one of the containers.

You should use "Docker Safe New Perms" or run New Permissions on individual shares so you don't screw with the permissions the containers setup for themselves in appdata.

 

Unlikely to cause a crash though.

Turns out to be plex docker crashing the server each night during it's maintenance run.  I've tried both binhex and linuxserver docker versions of plex and they both crash the server... Still trying to figure out why.

Hi i have the same Problem at the Moment so my Unraid keeps crashing every night. Do you have found a fix for  issue with the maintenance run?

Hello Jungle you can stop the plex container at your site for a while and see if the server still crashes. If this is not the case, I would activate it again if there is another crash. There's a very high probability that that's what it is. In my case it is unfortunately not the Plex Docker which is why I am still looking for the cause.
