Howdy
Not too long ago I picked up a NetApp DS4243 full of drives to finally stop running out of space on my desktop. I hooked it up to an older dell precision workstation running I had kicking around, via an LSI (et al) 9300-8e card, and all running the latest TrueNAS stable. I've also got an old APC BackUPS BR1000G capable of running the whole stack for a few minutes. All has been smooth sailing for the most part, and the last big checkbox before using everything properly is getting UPS shutdown functional. Of course, this is where it's all fallen apart a bit.
At first I thought I was having issues with NUT and the other components of TrueNAS that handle the UPS shutdown, as the system would throw many scsi bus errors and eventually hang the controller PC, requiring a hard reboot. Doing a force shutdown from software (upsmon -c fsd) shut down everything just fine, but actually yanking power to the UPS would cause everything to barf. While troubleshooting I decided to try a shutdown without the data line from the UPS connected and, to my horror, I had the same issue. So it's not related to the software at all, but a hardware problem.
I did the test again with the controller PC hooked up to the wall and only the DS4243 on the UPS, and had the same error. So it seems to just be very upset about the input power, for whatever reason. That particular scenario also causes the shelf to shut the disks off after a period of time, I think 5 minutes or so? Shelf still keeps running so far as I can tell but the disks all power down, light out and everything. Can be started back up by removing+reinserting them, but again I imagine the power changes are making things very upset.
I don't know of any way to get info directly out of the shelf's IOMs for troubleshooting, but I think it's safe to say that the UPS needs to be changed. My question is, has anyone else had a problem like this with a disk shelf freaking out from UPS power? Were you able to resolve it with a different UPS? The newer version of that same APC model (BR1000MS) specifically touts having "Sine wave output", perhaps that would solve the issue? I don't have a different UPS around to test, all roads lead to buying things. If it wasn't obvious, this has very much been a penny pinch setup, but if there's a place to spend money, I have to concede that a fully functioning UPS is where to spend it.
tl;dr my disk shelf freaks out when I switch to battery power and if I spend money on a new UPS I want to be darn diddly sure it fixes the issue.
