Drove FS - mount failed


I have a 10 year old Drobo FS. Shut it down to move some furniture it was on and now when booting it up, it fails to mount. I have tried the support article:

  • Running the repair (multiple times) - this only takes a few minutes, not hours like others report - normal?
  • Manually flashing the firmware back to 1.2.7
  • Shutting down, removing the drives, power on, power down, insert drives, power on.

Cannot seem to get it to mount. All of the bay lights are green and the dashboard is reporting the right amount of data. Have over 5TB, so pretty necessary.

Any thoughts? Looking through online posts, seems those steps above are pretty much the options.
