I have two luns concatenated to form one vmfs volume. Why is the total size of the extents less than the total formatted capacity? Other, non-concatenated luns do not show this difference.
The total formatted capacity of the LUN is identified as 719.25 GB
vdf output shows a size of 719 GB in Size and 91% used.
The two extents are identified like this:
This gives a total usable capacity of 660 GB for the vmfs volume, yet I have a total formatted capacity in excess of this number. The total formatted is considerably higher. High enough that I cannot account for the discrepency. Can someone help me to understand the difference?
