Unraid help

[Daemonpro]

hi everyone i was hoping someone could point me in the right direction 

 

so i have a unraid server with 2 power supplies and im trying to find a way to have unraid perform a proper shutdown when one of the power supplies fails

 

one psu is connected to the wall AC while the other is on a UPS however my UPS is not a smart UPS so no way to interface with it

 

any help would be appreciated ive been stuck on this for a few days 

 

 

thanks !!

I might try THEIR forums for this one... Pretty "out there" goal.

As Linus insinuated, this is going to be a bit of a challenge. Without the hardware/software interconnect a SmartUPS and OS that has a supported driver offers you would basically need to create this layer yourself. Now something like a Pi or Arduino that could check if line power is gone then trigger a relay to short the pwr pins on the motherboard for say 250ms or 500ms that'd work great but outside of this I can't think of anything else.

 

Best of luck.

Maybe just find a used very small capacity cheap smart UPS that you don't connect the server PSUs to just connect the USB or network interface to issue the shutdown commands. That's the least effort solution I can think of.

 

The other option is if your server has functioning IPMI (iLO, iDRAC w/e) is just query the hardware status of the PSUs through that then if one is not powered shutdown the server. A basic scheduled task/cron job will be able to do this.

Yeah I think its doable maybe a wemos D1 mini tied to the power switch pins on the mother board then a script/sketch with one of those amp clamps on each power supply or better yet a power monitoring Sonoff integrated with home assistant flashed with tasmota would be an option but I admit you have a bit of research to do but I think its doable and at a reasonable cost

okay thanks everyone for the advise ill try unraid forums see if theres anything, i enventually plan on getting a smart ups for the server its a old dell poweredge with 2 750 watt psu in it

Hey, not sure thiws is of any use but I also have a similar situation. I have a Poweredge T410 with a 2 socket + redundant PSUs of 750w each. I also have both idrac cards 6th gen.

 

I got into unraid a few month ago as i realized i had all this power and windows server os just didnt give me enough or without too many hoops to pass into for runnung VMs that run off linux. Here is what i have learned, idrad is not a system meant for OS access. You can utilize the tools available to access the drac interface but its the same as remote access. Because of the age of your server and i assume the version of drac, like for me, running custom scripts was a challenge a lot bigger than you might think as you'd have to have them accessible at boot using the flashcard slot of the drac. Unraid can access pretty much the same things as windows, mostly IPMI information and logs. I dont know how much more you can do with a newer server but pretty much any 12G server and before is not as integrated with the OS for everything thats the remote access controller
