Never mind, the answer is the extent_size is the number of sectors (or perhaps
it's the number of 512 byte blocks, I'll have to test on 4K sector
drives). So in this case 4M and 4M*3840 is the 16G (not 16M which was the
3840*4096).

Hi
extent_size is always in 512b unit and ATM it's 32b value.
extent_count is in 'extent_size' unit and ATM it's 32b value.
Volume size extent_size * extent_count (so 32b * 32b => 64b size).
Depending on your extent_size you are limiting maximum volume size.
Thus if you need to use Exa byte volume sizes you clearly need to go with 4G
extent size.
