My Drobo just went from four green drive lights to “data protection” mode, where they’re blinking alternate green and red. I didn’t replace a drive and no drive is flagged as having failed. What are the conditions which can bring this about?
This is a first-generation Drobo, 8Tb total drive space.
Later: The data protection phase only lasted about ten minutes. Now it’s got four green drive lights again. What the heck is with this? If I had to guess, I’d say that one drive hacked up a bad sector in the middle of a large-ish Drobo file system “region”, and the Drobo re-laid out the whole region. Am I anywhere near right?
Really, really makes me wish Drobo Dashboard could report detailed S.M.A.R.T. status from all drives…
