[Nut-upsuser] Synology NAS is shutting down Ubuntu servers after very brief power outage (fwd)

[Todd Benivegna]

Yeah I saw that.  Makes no sense.  I can Wireshark it, however even if I find the cause, I’d still have to go to Synology for resolution, which I doubt will ever get fixed.  Even if they do, I doubt it’d be any time soon.  Maybe that’s me being pessimistic, I don’t know, but I just don’t if I have the time or energy for all that!

Anyways, the power was out for just a few seconds and of course my servers shutdown on me after power being out for just a second or two.  Here is my syslog from two different machines.  I included everything just in case.

I just tested everything over the weekend and it all worked perfectly; cut power and machines stayed up until it was time to shut them down (I temporarily configured them to shut down after 5 minutes so I didn’t have to wait for the entire battery to drain).  I seriously at am a total loss.  I guess HDD Hibernation was not the culprit either since I’m still getting the same results.   Ugh.  Thanks everyone for all your help so far!!!!!

Unless you have the willingness to search & fix whatever stupidities they do in their unorthodox use of nut... just use a sane version
