Well, not sure why it happened but when I applied Windows Updates to our Exchange servers at work today they both had their database and log drives lose their mind and go from ReFS partitions to RAW partitions. So now I get to try to recover the data from them. I guess next time I go to do updates on said servers, I will be taking a snapshot of those machines first…….
I can also say I will never run ReFS on a server again unless I am not given a choice……
