I understand that the double recommendation is fine. Though, I am pressed by answering the referees about a submitted paper as they requested additional computation. That was going on until the host suspended access to sda. As I find risky to go on with one disk only (for a many days computation), could you please explain how to reactivate the removed sda, or format it to try if it recovers? I made some proposals in previous post. Or indicated that the best is replacing the disk with a new one.
