Install complete but TrueNAS keeps shutting down a few minutes after starting.

[rich1]

Motherboard : HP DL380e G8
CPU : 2 x E52450
RAM : 128GB
Hard drives 1x 3TB IBMESXS (boot) + 4 x 10TB Seagate Ironwolf Pro
HBA : LSI SAS 9207 8i PCI3
NIC : onboard 1gb + 10Gb SolarFlare SFN7002F SFP+ Dual-Port 10GbE Flareon PCIe 3.0

After installing truenas all looked fine and tested read and write speed from an nfs client - seemed ok.
Then I did two things after which truenas started shutting itself down even after restarts - it stayed up for about 3 minutes i think.
The two things : from system off state I plugged in the 10gb cable and started the system - all seemed fine then shortly after that I enabled ssh service from the web app.
About a minute later the truenas went into a shut down.
After restart it shut down again after about 2 or 3 minutes - just enough for me to find that the ssh enablement was reverted seemingly automatically.
I also disconnected the 10gb card - made no difference.
Very hard to debug because the machine keeps shutting itself down after rebooting - so I can't look at any log files !

Any recommendations ? how do you examine log files ?

I you haven't done too much work on it already I just would start over. And this time, before every change, make sure you save your config file before you apply that change. That way if anything goes wrong you can reset your hardware to the previous state, reinstall TrueNAS and load your latest "safe" configuration in no time at all. I know this is the easy way out but it beats searching for a solution for hours to get things running again. It gives you the time to research what possibly happened while you have a working system.

Your logs should be somewhere in var/log, but I am not sure if the logging is persistent. This might be helpfull. It's about FreeNAS but I am very hopefull it's applicable for TrueNAS as well. So the next time if anything goes wrong, you know where to look for your logging and maybe learn something out of it. You can always hope.

thanks @Evertb1 - that's what I did pretty shortly after experience. Thanks for the link - looks like it might be a solution for next time. I guess before using this setup for real i will need to get some kind of remote logging working because a rebuild will not be a great option
thanks

I don't know if you have gone trough the proces of reinstalling and uploading a config file already but it is really not bad. I have done it a couple of times with a FreeNAS system and it hardly took 5 minutes more then the actual reinstall. No problem at all.
