I have an odd problem and I'm definitely not the UPS expert.
The issue: Every few days, I'm not sure what the periodicity is yet, it has only shut down twice so far over I think 5 days maybe, I will obtain exact date/times when I do a little more digging. The UPS is powered off, no alarm, and when I bring the system back online, it comes up without any alerts on TrueNAS nor ESXi. But none of the logs say the system is shutting down which I think is odd so my initial thought is the UPS suddenly powered off.
I am looking for a possible way I could troubleshoot this strange problem. The details of the system are:
CPS LX1500GU UPS, USB port passed through to TrueNAS VM.
ESXi 7.0 (with current updates)
All of my system description is in the link below.
This system has been running fine for years. The only change I've made is recently installing TrueNAS Core 13-U5.1 and U5.2. I do not recall this happening with U5.0. And I'm not pointing a finger at TrueNAS, its just a data point to consider. ESXi was last updated about 5 weeks ago to build 21686933 and I don't think it's ESXi.
I have examined the TrueNAS /var/log/messages file, it only shows a routine event at midnight and then the system booting up when I powered the UPS back on. I have examined some of the ESXi logs and that was Greek to me.
I also examined the UPS status using (upsc ups) to list the data, nothing odd there either.
My current plan of attack is to swap the UPS unit with my personal computer. Both are CPS 1500VA units, that is about all that is similar. This will allow me to rule out or confirm the UPS is at fault. It could be the UPS batteries for all I know however I have not lost building power during the period TrueNAS stopped recording log data so if it were a battery, external power should have kept it going. Maybe the UPS has a failed internal component.
I'm posting this in case someone has experienced this before or has an idea on a path forward. Is there any specific log data in TrueNAS or ESXi that might shed some light? For now I will swap out the UPS units and see what happens.
Thanks for humoring me.
