Reboot in safe mode Start Array in safe mode (this worked) Reboot in normal mode Array started successfully upon reboot. So, the issue is resolved for me. But leaves me a bad impression of quality of unraid. The server was down for several days until I found out there was an issue because one of the self hosted app was unreachable. I was considering sharing the server with family and friends. But now, I now have my doubts. Unraid has been quite solid for me in the last 9 months when I first installed it. Maybe I should stop installing updates. Or consider other alternatives.
