Hello Everyone!
I put this system together not so long ago, and most of the stuff is running and I was able to troubleshoot. But sometimes it crashes, and can't figure out why. If anyone has an idea or can point me in some direction, I would be happy. 🙂
Symptoms: webgui doesn't load, shares are unaccessable, fans are running.
Since I have Pihole running on it, and my desktop and phone points to it as DNS server, the connection to the internet is not working on the said machines. If I leave it as it is, doesn't recover, after cold reboot everything start up fine (array, parity check, docker containers). Timing looks random. It happened usually the early morning hours, but happened also at 11:40.
Uptime is also random, sometimes a week, sometimes it doesn't even reach 24h.
System:
Acer Q67H2-AM mobo with i3-2120
6GB RAM: 2GB Kingmax + 4GB Crucial
PSU: Cooler Master Elite Power 500W
HDDs: 4x Samsung HD204UI 2TB
What I ruled out:
- no cache - > no mover
- no Vm
- RAM: memtest86 found no errors
Syslog: doesn't show anything. (Crash happened between on 28th, 8:03 and 12:32.)
Tried to capture with local syslog server and mirroring to the flash, but there is nothing suspicious.
Once the stats tab was running in my browser on my desktop PC, when the crash happened. I saw very small activities on everything, so CPU, network and disk usage were barely visible on the graphs. The RAM showed the usual values, around 3 gigs used, around 2-300 MB free, the rest is cached, which should be normal in Linux based system afaik.
From the Docker logfiles: I couldn’t find all the logs but I can post them, as I copied my whole appdata folder to my desktop after this crash.
I checked the following dockers: Jellyfin, Jackett, Lidarr, NginxProxyManager, Ombi, Qbittorrent, Radarr, Readarr, Sonarr.
I found, that the crash was between 8:03 and 12:30. The Ombi logfile had the last timestamp. Nothing suspicious was found, only normal sheduled tasks running successfully.
I suspect a PSU fault, but I would like to rule out the SW side reasons. Currently I don't have a spare PSU to swap and test it.
Any ideas are welcome. 🙂
