We have several clients running into this issue with the latest one being on ver 6.0u2. What happens is that I’ll try to edit a VM, when I click OK even without changing anything, it throws the error “The disk capacity specified is greater than the amount available in the datastore”. The datastore of the current one I’m working on is 500GB in size and the total amount committed + used was less than 400GB. It almost seems like it’s not calculating the used space and only looking at the free space available.
I have been unable to find a solution for this. Does anyone have any hints on how I should go about resolving this issue?
