In my 4-bay drobo the top drive is suddenly constant red. The dashboard says my Drobo is critically low on capacity and that I should replace the hard drive indicated by the red light with a larger hard drive.
This puzzles me. I have this setup:
Why does it ask to replace one of the 4 TB drives and not one of the smaller 3 TB drives?
Does this make sense? Could it be that the dashboard is wrong? And what would happen if I takeout one of the “green” 3 TB hard drives and replace it with a 4 TB harddrive? Wouldn’t that make more sense?
