 Also, is there some kind of "simulate shutdown setting"?

You can always plug the power lead to the computer into a regular socket the wall/extension lead and then yank the ups power cord to test.

That is NOT plug the computer into the ups.

 

If the shutdown works like it should the computer will turn of, but not start again when ups power is back tough.

If the shutdown does not work like it should then the computer will stay on, leading to much easier troubleshooting and no need for parity checks if the shutdown does not work like it should.

 

 

Also are you sure that the battery is ok?

Had problem with my then 6-7 year eaton that said the battery status was fine and it worked fine on battery for 15min if shutdown was off and i manually shut it down fine and started fine again after power was back.

But shutdown set to 3min like i usually have (to save battery life) it would shutdown but not cleanly and a parity check was waiting on startup.

 

Did not mess with it for a couple of months since my outages is less then 1min 98% of the time.

Then i wanted to get it ok again and checked, battery status was still fine.

BUT it did not want to work for more then seconds and when started again it was at a very low battery and charged very quick.

Ok battery is dead so bought a new ups (since i hated how it tested with a high squeal and fan noise so often) instead of a new battery.

A day or two later i connected it to my windows pc and eatons program and even that said the battery was perfectly fine, but NO it was stone cold dead.

I´m pretty sure i read something about to short % or time can cause problems.

And also that it can work for a while but then when batteries wear down starts to cause problems.

But i´m not 100% sure about this, i can have it mixed up with something else and it was a few years ago.

 

And i think i did have some problem with using a high % on my last ups many years ago, that i solved by using time instead.

Since then i have used shut down after 3min and it has worked fine chosed 3min because when power come back here it almost always shuts of again after 10-20sec and come back after 5sec 3-4 times before it stabilize.

 

So try a lower % or try time instead and maybe not to low of a time.

And remember when trying this do not have unraid power in the ups (only USB cable).

Connect the power to a regular outlet so IF the ups cuts power to early you won´t get a unclean shutdown and a parity check.

As long as you connect the USB cable unraid and ups will talk to each other normally and will initiate a shutdown when you yank the cable or use a on/off switch, so just look/listening for when unraid shut off and see if ups turn of before that or not.

I guess if you really wanted to be cautious you could disconnect most of your drives in your Nas

No need to at all!

Just connect the Unraid power cord to the wall directly instead of the UPS.

Then plug in the USB into the UPS and initiate a UPS shutdown for example by yanking the UPS power cord.

Everything will behave as if the unraid computer is plugged into the UPS and unraid will still shutdown if all goes ok, besides that IF something goes wrong like UPS battery gets too low unraid still has power and will not shutoff from low battery.

I have just noticed, following a short (few seconds) power outage that there is no UPS failure notification/event in the log file.

 

I do not use NUT anymore but i could swear that i got them in the log file when i did.

So maybe a power failure test is in order to see if unraid do shutdown like it should?

Before trying anything with a UPS do run unraids power (and/or any other computers) from the wall so when the ups shutdown there is still power to unraid/computers.

Shutdown swap power lead/plugs start up test ups.

You do avoid some problems this way IF there are a problem like an unclean shutdown and a parity check for hours.

 

Ups functions will still work like normal for example the status and the shutdown (if noting locks the array) since all that is done trough USB/network depending on ups and chosen way.

Do not have an answer for you, only two small tips too try.

i would probably have tried running unraid as master and synology/pfsense as slaves and sees how that goes, then if not ok tried pfsense as master.

 

Also when you are testing do NOT have the equipment that you are testing on (synology/unraid/pfsense) power cables in the UPS just plug them in a normal outlet, that way IF the battery runs out and the ups shutsdown the equipment still have power=no more unnecessary parity checks/powercuts.

Learned that a few weeks ago while pretty much feeling like a moron that did not think about that my self, i mean after i learned it, it is so obvious!
