I don't think you are doing anything wrong per se. By default, the nut slave (pfSense) isn't going to initiate a shutdown until the master server declares a low battery condition. This is different than a low battery warning.
When the master declares a low battery condition, it will send a notification to all the slaves indicating that there is a pending loss of power. The slaves will each disconnect from the master and then initiate their own shutdown. Once all the slaves have disconnected, the master will initiate its own shutdown.
If you want to override how the master determines when to declare a low battery condition, see the section on "ignorelb" in the ups.conf man page.
After doing more research I found out, that not only my pfSense-Box wasn't shutting down. It was just the first one I tried. So there seemed to be a problem inside of nut, not inside of your plugin.
So I did more research, did deeper looks into the code and found a bug in the nut-driver. Posted the issue on GitHub: https://github.com/networkupstools/nut/issues/460 then I fixed it: https://github.com/networkupstools/nut/pull/461/commits/b82b9cf3b4695f3171b6250af431a6a3f7fc81c4 and did a pull request: https://github.com/networkupstools/nut/pull/461
It then has been reviewed and merged into nut https://github.com/networkupstools/nut/commit/bc6ca11be42281e6d7f36dc6cf2860c2fe950f66And now my problem is gone :) So: You were right, I wasn't doing anything wrong per se.
But thank you for your hint with "ignorelb" as this will help me with another problem when using apcupsd and nut at the same time :)

I plugged the UPS into a 2K12 server and installed CPs PowerPanel software, let it run for few days and didn't get any LOWBATT messages, then plugged it into my FreeNAS server which is using driver 2.7.3, internal driver .39. and no LOWBATT messages.
So, something is not the same after the upgrade on pfsense because i dont see the LOWBATT message on 2 other boxes. Going to try mirroring the freenas NUT configs, (being doubtful that will matter) then going to have to find some time to reinstall pfsense to 2.3.2 and go from there).
When you put it back on the pfSense box did the LOWBATT messages immediately return?
No
Bulldog, did your issue get resolved?
Hi, it seems that adjusting the following has kept it quiet. Thanks again.
battery.charge.low: 20
battery.charge.warning: 25 -

Just FYI, the PR for the dummy driver has gone in. The shutdown issue will have to be addressed in a follow-on release. This issue will need an enhancement in the core so it may have to wait until 2.4 is release.
-
I have. The power kill logic is gone from the base os level. Still searching to find out when and why.
Being a long time NUT user with pfSense this made me curious. Is this a new problem recently?
I've been adding stuff to rc.shutdown for "ages" to get proper shutdown-killpower-restart loops with a couple of APC serial ups-es:#Final shutdown stuff, UPS if /usr/local/sbin/upsmon -K; then # Warning message echo "POWERDOWNFLAG detected - Power cycling the UPS loads..." # Do shutdown /usr/local/sbin/upsdrvctl shutdown #Might be needed for power races # /bin/sleep 180 # /sbin/reboot fi -
The problem pre dates the current generation of the NUT package, but I'm not sure how far back it goes.
What needs to be done is pretty much the same thing you are doing with your patch to rc.shutdown, except that I need to genericize it so that it can be used with other packages such as apcupsd.
-
OK, thanks for the update
And nice to know that I didn't misunderstand anything with my fix, although it would be nice not having to remember the manual rc.shutdown patch every time pfSense is updated.Thanks, keep up the good work!

I upgraded NUT on pfSense to latest 2.7.4_5, and ever since I did that, it seems there is a high uptick in UPS communication errors. It's possible that it's another environmental condition that is going on here, but wanted to see if anyone else has had issues. PfSense is running on a small physical box, and it is directly connected via USB to a CyberPower EC650.
I've been getting flooded with emails as a result of this (yes, I know that I can turn them off). But it points to something else that is going on. Here is a dump of the ups related events for a small window on 9/4. In the last 24 hours, I have 232 events that are the Permission denied error.
One thing I did notice, if you look in /usr/local/etc/nut, all the *.conf files have perms of 640, but all the *.conf.sample files have perms of 644. Not sure if that matters or not, and also not sure if that's "new" or not.

The event itself may be very brief in duration, but is logged as 5 seconds due to the polling interval. There are several reasons that a momentary transfer to battery can happen depending upon the UPS.
Some UPSs allow the variables which control transfer to be changed. The complete list of variables supported by NUT can be found here. To see what your UPS actually supports, use the upsc command. For transfer items, look for variables "input sensitivity" or "input.transfer…"
Be careful with these. :)

I believe that

are just voltage threshold? Am I right?Should I try change input.sensitivity to low? If so - where to put it in NUT settings page?
-
Why would you be doing any such thing? The UPS is doing its job, just leave it alone.

Yes, those are the voltage levels that will trigger transfer.
Setting UPS variables is not something that you do in your NUT config. You set them in the UPS using the upsrw command.
As Dok notes, the UPS is doing it's job, protecting the attached systems from excessive power fluctuations. You might want to investigate the source of the voltage problem before turning down the sensitivity. Consulting with the UPS manufacturer might be a good idea as well.

dennypaged, oktornotor, thanks for answers.
Agreed, the UPS is doing it's job. I'm just trying to avoid annoying mail reports (at the night time especially).
Another SMART UPSes connected to same power input do not have any complains about power conditions. -
Denny (or whoever else wants to lend a hand!),
Running pfSense 2.4.1 as a firewall and router, with NUT 2.7.4_5. I have the pfSense box, a FreeNAS server, and another FreeNAS server (Replication target) all on a CyberPower CP1000AVRLCD UPS. (My switch is also on that, a 16-port Netgear item.) I currently have my FreeNAS server as the master, and both the backups box and pfSense are "seeing" the master no problem. When I pull the cord on the UPS, I get three nice e-mail notifications (one from each of the boxes), and all boxes shutdown in an orderly fashion when ordered to by the master (tested both Battery Low and On Battery, the latter with a 10 second timer in my tests).
The problem is : none of the boxes start back up when I plug the UPS back in! I'm sure this is something dumb, because I'm not that knowledgeable at all - but what I CAN say is, the blue LED is lit on the UPS (but the display itself is blank). As in, it's not shut down. If I press it, it goes completely dark, and if I press it again, it lights up again, along with the LCD display and all - and, voila, most of the boxes start up. That is, both FreeNAS boxes start up - the pfSense one needs to be started manually. All three boxes have Always On setting in the BIOS for waking up after power loss.
Any ideas…? I think it would make more sense to have the box doing the routing (pfSense) also being the master, but I'm not 100% sure how to configure that. But the better question is - do I need to? Would that fix anything?
Thanks in advance, and thanks also both for all your work on this package, and for the continued support you offer to us plebes on this forum! =)
Cheers!

Can you clarify what you mean by “the pfSense one needs to be started manually”?
Traveling, so expect delayed responses…
Thanks.

Thanks for the quick reply - far from "delayed"!
I mean I have to physically push the power button on the pfSense box.
Enjoy your travels!

This is kind of a known issue…what should happen is that the master should shut down the UPS before the UPS fully drains. In your case, the master is your free NAS so you likely need to look there.
I reported this issue back in June or so. Now that 2.4 is out I believe a bug fix for the nut package for pfSense can be released to fix this on the pfSense side. But I don’t think this will help you out, as it sounds like the freeNAS isn’t shutting down the UPS prior to fully draining it.
