      @dennypage Do you have any ideas why this would happen in a Synology NAS when it is connected to the pfsense NUT server?

      It's not related to the pfSense NUT package itself. It could be a result of how Synology manages NUT, or how Synology manages boot up. Either way, the best place to seek help would be the Synology forums.

      One question comes to mind to prime the pump... did the Synology actually complete its shutdown? Did it remove the POWERDOWNFLAG?

        It wasn't really acting up this way before, so I'm not sure what changed.

        I wouldn't really know because Synology doesn't provide logs regarding the complete shutdown but what I do know is that it will only go to safe mode with all the lights in the NAS itself lit up but with no activity (unmounted volumes, stopped services, etc.) which it did reach. If it was an improper shutdown, it would tell in the logs too. How would I confirm if it did remove the POWERDOWNFLAG?

            Here's the response from Synology:

            After discussing with our developer, we collect the time table as below:

    12:00:24 AM Server is on battery. - AC power fail, UPS on battery
    12:02:45 AM Server going to Safe Shutdown - enter safe mode (it will not shut down the NAS immediately but keep it on safe mode if you didn't enable the option "Shutdown UPS when the system enters Safe Mode")
    12:?? AM - We suppose that UPS stops output the power to NAS so the NAS shutdown. Unfortunately, there doesn't have any log here cause by the current design.
    12:27:05 AM System started to boot up - UPS power retrieved, reboot the NAS. 
    12:27:59 AM Server going to Safe Shutdown - When the NAS is rebooting, the UPS status changed to "on battery" and low battery, so the NAS will not show "server back online" log but enter in safe mode directly after rebooting completed.
    12:28:06 AM - During the NAS enter the safe mode, the disk 4 and 5 in the expansion unit cannot be recognized in a short time then disabled by the system. Originally, the expansion unit will reset "all SATA port" then retry the link. However, it is during the safe shutdown so the expansion unit is also during the shutdown procedure, it would lead to disk 1 to disk 3 SATA link down directly as well. In conclusion, all expansion unit HDDs are disabled at the moment. [1]
    12:30:07 AM Server back online- AC retrieved UPS power retrieved, NAS starts to leave safe mode.
    12:31:19 AM System started to boot up - System force reboot after leave safe mode, it is the current policy.
    12:31:40 AM The RAID of Storage Pool 1 has been reassembled.- When the system reboot, it tried to assemble the RAID. However, all expansion unit are disabled previously so the RAID cannot be assembled normally then system try to force assemble the RAID. [2]

It looks like the disk 4 and disk 5 model ( WD100EMAZ-00WJTA0) are not stable with the NAS. After checking the HDD compatible list, it also doesn't list in it. Therefore, we cannot ensure the stability with the NAS or expansion unit

To prevent this issue, please refer to our below suggestion:

1. Replace the two disks in the expansion unit to the compatible model.

2. The log shows the UPS has on battery/power symptoms frequently. Please double-check the UPS status and AC power stability.

            I will not replace my expansion unit's disks 4 and 5 because those are brand new 10TB drives that I shucked from WD Easystore drivers and are known to be stable with Synology NAS'es, that's not the issue.

            I wanted to specifically understand the 12:27:59 AM event though and I hope you can share your ideas too. If I understand correctly, they're saying that when a UPS comes back on after a power blackout and is still in charging/low battery mode, the NAS detects that low battery condition and will go to a 2nd safe shutdown mode even though there is no FSD signal sent by NUT? If so, then that really isn't good.

              I think I really need to implement the Ups.delay.start now. Where do you put it though? I tried putting in the extra arguments to driver section and the service won't start afterwards.

                So does that mean that the ups.delay.start variable is not available for my ups? If so, any other idea how to get around the issue then?

                  I wanted to specifically understand the 12:27:59 AM event though and I hope you can share your ideas too. If I understand correctly, they're saying that when a UPS comes back on after a power blackout and is still in charging/low battery mode, the NAS detects that low battery condition and will go to a 2nd safe shutdown mode even though there is no FSD signal sent by NUT? If so, then that really isn't good.

                  This makes good sense to me. A low battery condition indicates that power could be removed at any time. In general, you don't want the system to be attempting recovery of RAID in a situation such as this.

                  On a separate note, you have some disk issues as well. I'm not sure it's a good choice to dismiss discard Synology's advice so casually. If you want a stable NAS, you should stick with enterprise drives. This is one of those "you get what you pay for" situations.

                    It's not available via NUT. It could be controllable via some other method on your UPS.

                    That your UPS is restarting while still having a low battery is somewhat problematic. You may wish to discuss this with the UPS manufacturer.

                        @sauce That looks like a generic package install problem, failing during install of net-snmp. You might re-try the install, perhaps following a reboot, and if it fails again follow up in the general pfSense packages forum.

                            I'm having a bit of a problem with nut and pfSense.

                            I want to have pfSense shut down when low battery is at 30%. I tried at the default 20% (Eaton 5px) and I found it just did not leave enough time for pfSense to gracefully shut down.

                            I have configured nut as per below:

                            nut.png

                            However, in my logs I get the error "dstate_setflags: base variable (battery.charge.low) is immutable". It is literally flooding my system logs.

                            Am I doing something wrong? Nut seems to ignore the ignorelb command and is still waiting until low battery gets to 20% (as reported by the ups).

                            I have also placed the below arguments in the ups.conf section to no avail. However, there were no error messages in the system logs.

                            community = private
                            ignorelb
                            override.battery.charge.low = 30

                            I'm guessing I am doing something wrong but can't work it out. If it helps I am running an Eaton 5px with network-ms card

                              "20 %" should leave you with 30 seconds or so, probably far more.
                              If non, the battery isn't in good shape. Or the UPS overloaded. Which decreases battery life / shape.

                              I advise you to check out the NUT support forum.

                              No "help me" PM's please. Use the forum, the community will thank you.
                              Edit : and where are the logs ??

                                The "ignorelb" option literally means that you want to ignore a low battery condition signaled by the UPS. Unless your UPS sends a low battery indication immediately upon going to battery, this probably isn't something you want.

                                battery.charge.low is a value managed in the UPS. You are trying to set it, and don't have SNMP privs to do so. This probably isn't something you want either.

                                SNMP is polled at 30 seconds. This means there is an up to 30 second delay before nut knows it is on battery, and up to 30 seconds before nut knows that the battery is low.

                                In general, if you want to shut down sooner it's better to look at runtime remaining than battery charge.

                                  The ups is new, only had it for approx 1 month. It is not overloaded, have pfSense, freenas and a couple unifi switches.

                                  Thanks. Should I set the default polling time to a lower value?

                                  How would I go about setting a runtime remaining configuration in nut?

                                    As to the NUT config, it all depends upon how much runtime the UPS has in general, and how much runtime is remaining when the UPS signals a low battery situation. If the UPS has 3 or more minutes of runtime when entering low battery, I would simply let the UPS handle things. If it has less, you may want to shorten the pollfreq.

                                    Given that you have a snmp management card, you likely have a good deal of configuration available in the UPS to control when low battery state is entered. The UPS is generally a better place to drive decisions than in the NUT configuration.

                                      I recall my Eaton 5PX throw OB (on battery) and LB (low battery) at the same time, even with a large runtime remaining. In your UPS configuration you can configure the shutdown timers as Denny mentioned. Heres my 5px shutdown parameters.

                                      If at 20% your UPS is failing to shutdown pfSense its likely your batteries are toast. Even new UPS can sit on shelves for sometime so worth testing before putting into production use.

                                        Thank you for the screen shot.

                                        Under on battery, the values of 1800 seconds and 20% does that mean both of those values have to be met before the ups Initiated a shuts down?

                                        If I wanted pfSense to shut down at 30% battery, would I pull the mains and see time remaining at 30% and input that value in to remaining time and shut down duration?

                                              minimum remaining battery capacity level from which the shutdown sequence is launched.
                                            • Shutdown after (0 to 99999 minutes, not validated by default) is the operating time in minutes left for
                                              users after a switch to backup before starting the shutdown sequence.
                                            • Shutdown duration (120 seconds by default) is the time required for complete shutdown of systems
                                              when a switch to backup time is long enough to trigger the shutdown sequences. It is calculated
                                              automatically at the maximum of Shutdown duration of subscribed clients but can be modified in the
                                              Advanced mode.
                                            • If battery capacity exceeds Minimum battery level to reach before restarting the UPS after utility

                                            At the moment, FreeNAS shuts down after it has been on battery for 5 mins (configured via FreeNAS).

                                            I would like pfSense to shut down when battery is approx 30% and the ups to shut down when it hits the low battery state of 20%

                                            Will have to play with a few of these values. I read through the ussr manual prior but damn it confused me!
