We are at the point where we have 3 DFS servers and they are becoming full, we will have to upgrade the drives.
My biggest worry is when I take a server offline, replace the drives, and put the server back into production, the DFS service will think the blank drives are the one's that are up-to-date, and then begin to wipe the other two to model them. At the same time, if I copy data to the new array, and then put it back into production,, I'm afraid of any data that was written in-between the downtime would be deleted.
Is there proper procedure to follow to do this?
