Increasing Datastore size is empty.

Hi all,

ESXi 5.5.0 Build 2068190

I have run out of space on the disks that I have in the system. I added 2 more drives to the array and expanded it. Now, the datastore is 459.62GB and the total disk size is 929.00GB.

When I click the Increase... button I get this screen.

I don't know why I cannot expand the datastore on the system. I imagine that I can fix this issue by reinstalling ESXi or by recreating the datastore but I was hoping I wouldn't have to go that route. Any information that could help me out here?

Thanks Charles
