Hi all!
Tonight something really strange happened. I am using two VM, an ubuntu with pihole installed, and another with opnsense.
Seems that exactly at 3 am both VM stopped. I noticed that becouse Internet was not working. I hadn't the time to see the logs and investigate becouse I needed Internet immediatelly. So first I tried to start again the VM, but it was not working (the web interface says that the VM has been started with a green toaster, but the main screen says stopped). So I rebooted the whole system and so it worked.
Now that it's all working I would like to investigate at what happened, but on /var/log/messages of Freenas I see only messages from when I rebooted the server. What can I do to find the problem? What could be the trouble? VM seems to me pretty stable since now.
My specs:
Freenas 11.0 U1
Xeon E3-1230v5
Supermicro X11SSH-F
64 Gb ram ecc
6 WD red 6 Tb on raidz2 + 1 WD Red 3Tb on a single volume
Temperature were cool (it was also night), and today I don't have any activity scheduled on FreeNAS (scrub, smart tests, etc).
About the ram, I have dedicated 512 mb to pihole and 768 to opnsense. I also have 6 jails but with low activity.
