I have freenas running a dell R710 and I finally realized its been restarting on me almost since the beginning. I would occasionally have my mapped drive to it disconnect. Which was the only symptom I ever really saw.
Finally one day plex (running in a jail on it) wouldn’t respond. I logged into idrac to realize it was rebooting. Software only though. No extra noise from the hardware spinning back up like you get from a cold boot.
Everything I see looks fine except in the debug I can find “unscheduled system reboot”, “The operating system successfully came back online”. I have been through the messages file in /var/logs/messages and cant find anything. Same in idrac. It all checks out as far as I can see.
So my questions are,
What part of the debug should I attach or just attach the whole thing? (I havent been able to find anything other than what I stated above. But this log style is new and confusing to me.)
Any other suggestions on where to look for logs?
And any suggestions on troubleshooting?
