I don't quite understand as I am not going up to 2TB - 512bytes. Are you saying that because I have added to many disks to the SAN that this may be causing the problem?
I currently have other another LUN that is large but defined in Vshare with Block size of 1MB and it allos me to define a vdisk upto 512GB. So why will a Block size of 4 MB not give me the same capacity?
Do I really lose that much space??
Thank
