All, I'm having an issue suddenly with Unraid. It started yesterday when my array spun down and unmounted randomly. I started the array and noticed shortly after that it had unmounted again. I figured that a reboot was in order and I went ahead and updated the firmware per usual (used USB creator then replaced config file with old, added license). When I booted with this new firmware, the system lost power and rebooted automatically. This process now repeats over and over and I can watch it happen. As soon as I get to root login, power is lost, and system reboots (not just unraid but my server). I did some troubleshooting. I reverted to the old firmware and nothing changed (same problem). Then, I did a fresh install of unraid (6.7.2) without porting my configs over. This would allow me to see the web GUI. However, as soon as I try to assign drives (have screen shots so I know I'm assigning them correctly) the system loses power and reboots. I ran a memtst (admittedly only for a few hours) but I don't see that as the issue here. If I don't assign any drives, the system will never lose power. I've thought about the SATA and power cables--they have all been re-seated with no change. I can see all of the hard drives in bios and in unraid. There is no indication that there has been a drive failure (appear as "healthy" in unraid while not assigned to the array. In addition, I can feel the drives spinning when I press my finger to them--so I'm pretty sure they are getting power and the system can see them. Any ideas as to what could cause this? I feel like it has to be a hardware issue but would rather not go through replacing every component until I find the culprit--I'm hopeful that someone might be able to point me in the right direction.
