Hello...
Yes, the logs provided should have had an instance of the raids syncing... but I had done this procedure with only the NVMe installed, so no HDDs on the 4 bays. Probably this happened before I decided to format the USB boot drive and try again from scratch...

The UPS I am using is compatible.. it's the APC Back-UPS ES 750 listed in your website. Just for kicks I turned off the NAS a couple of days ago, tested the UPS by itself, connected only the NAS again with the usb of the ups plugged, and a couple of seconds after I turned the NAS on, it turned off again... I don't really want to repeat this with the 4x HDDs inserted as I don't want to corrupt my data...

I will try to get my hands on another UPS (also compatible), turn off the nas, disconnect the 4HDDs and try again... hopefully I don't loose my data. I have a backup of it... but the problem is that's almost 22TB, and it takes a looong time to put it back on the NAS...

any other suggestions?

Have you tried the UPS on a desktop system and the APC Powerchute software? I'm wondering if the USB cable is defective ....

hi Gremlin... yeap, tried three different cables.. you might have missed that, but it is in the first post... I'm going to try to get my hands on another compatbile UPS...
