I had the exact same problem. In the end, I re-imaged my flash drive from a backup. That still didn't work. Then after rebooting the server around 10 total times, it eventually started working randomly. That was about 2 months ago, and it seems to be continuing to function... I don't really have anything too helpful to add, sadly. My theory is that something just doesn't work right when the server reboots from a UPS-driven shutdown. As I said, what happened to you was pretty much identical to my experience.

Hello. I've been using Unraid since around 6.6 or so, and for some reason I have had more issues in the past 2 months than ever before. Most recently, starting yesterday out of the blue, my array seems to suddenly get random tiny (several kB/s) reads constantly. This appears to potentially correlate with a nonstop, "pulsing" blinking of the HDD activity LED on the case every single second, all day. As a result, my array will not spin down, and if I manually spin it down, it instantly triggers high CPU activity and the array coming back online. I'm attaching several relevant pictures to show my general config.
