I moved an entire VM's folder from one datastore to another, using the ESXi 6.7 web interface to do so.
I had forgotten that the second drive, which is massive in size, was also in that folder.
So the web GUI started the move and eventually the new Datastore ran out of room.
Now I've got half of the vmdk in one Datastore and half of it in another Datastore.
Is it possible to merge them back together again on the original Datastore that has plenty of room?
Original Datastore on top, new Datastore on bottom.
The VMDK being discussed is circled in red.
Next time I'll use the command line to "copy" rather than "move" files via the web interface.
This is what happens when you're in a rush and aren't paying attention.
