RN312 - programatically eject external USB storage and programatically shutdown RN312.
I am faced with unexpected power outages (here in CA). My RN312 is on a UPS, but sometimes the outage lasts longer than the UPS battery. I monitor the battery state on a separage windows system that ...
Thanks StephenB ,
This your suggestion would work (letting NAS monitor the UPS), but shutting down the PC's manually wouldn't work, if nobody is around (which is often the case).
The solution you referred to in the older post "rnutil rn_shutdown" works perfectly. I tested it and the USB external drive was properly shutdown followed by the NAS itself.
The PC monitoring the UPS now has an script that fires after 10 minutes on battery that, among other things, sends an ssh command the RN312:
ssh root@nas -command rnutil rn_shutdown
Perfect solution. Thanks.
Generally its best to have the RN312 monitor the UPS over USB. Windows PCs and Macs that don't use RAID are less likely to be adversely affected by an unclean shutdown. So I'd switch to having the ReadyNAS monitor the UPS, and shut down the PCs manually. There's less risk (and it will work even if you are not home).
But to your question: the info in this old post should work: https://community.netgear.com/t5/New-ReadyNAS-Users-General/How-to-shutdown-my-ReadyNAS-Pro-4-RNDP4000-OS6-10-0/m-p/1748742#M36569 One mistake in that post: you should use root (and not admin).
The shutdown should also eject the USB drive (though that is not something I've tested, as I don't connect USB drives to my NAS).

Correct. If the UPS battery drains, the PCs would do an unclean shutdown. In my experience, that isn't a problem. Though I don't tend to leave documents open, etc. on my PCs.
