Replaced drive with larger drive but

My drobo recently displayed a red light. I replaced the 1TB drive with a new 2TB drive and let the RAID rebuild. However the dashboard is still displaying old disk capacity (drives are 1,1,1,2 - Capacity = 2.69TB). IS there something else I need to do to get it to recognize the additional space?

FYI: The dashboard does display the correct drive capacity.


This is because, the largest drive (2 TB) is used as a redundancy drive. Meaning, you effectively still have 1+1+1 = ~3TB of usage.

You need to replace another drive to see an increase in your available space.
You could use this calculator to calculate your available space from any disk drive setup.
