    • Degraded Array (missing one disk)

      So the hard drive is still there and functional (no smart errors) as far as I can tell, it just says removed from the array within the raid section. I noticed this after deleting no exec from the config file but it could have happened earlier but i just didn't notice. I am just hoping someone can post code for shellinabox to add the drive back to the array. When I click recover the drive isn't an option.

      Printout below.
