Through the perl SDK I have created a number of delta disks on a virtual machine that all point back to the original backing, not through each other. The disks seem to work wonderfully, however when I go to delete them I get a handful of faults. It seems that the first delta disk that is deleted also removes the primary backing, and the other disks have no where else to point to, and will throw faults when you try and remove them, citing a lack of the primary backing. Even if I attempt a batch operation, deleting them all at once, a fault will be thrown saying I can not complete the operation that way as well. Is there any way to delete the delta vmdks with out deleting the primary backing? Alternatively is there a way to not have the primary backing be deleted until the last delta disk backed on it is removed?
