I am attempting to create a new partition from a 3TB Fusion Drive on Mavericks, but Disk Utility won't allow it. I successfully created a partition from the same drive last month, so I am not sure why it won't allow me to create another one. Does this have something to do with the Fusion Drive? Is there a workaround?
Thank you.
