I've been battling this for going on 3 days now and have made no progress. I was able to plug one of my cache drives into another machine and make a clone image of it (now i have to go through hell to mount it), but i cannot for the life of me figure out why this happened. I woke up to a frozen Unraid box, rebooted, and when it came back up, all my VM's were mysteriously missing and my Cache drives were labeled as unmountable. Any ideas? If i lose all that data, I'm gonna freak.
