In the attached image you will see that Space used grew by 400GB yesterday. Yet there is only one LUN in the volume and its size is 800GB while the Volume is 1.49TB. Capacity Used on the volume is showing at 1.19TB. BUT there are no snapshots as shown in the screen grab. I did receive a message today with the controller complaining that it needed 110GB MORE space to create first snapshot. So that would be part II to this question. Why does this first snapshot require still more space? Thank you.
