Resizing a LUN to 90% of Flex Volume

Hi

I have 4 CSV LUN's for Hyper-v Cluster.

Each volume is 500 GB (thin provisioned), with a 250 GB LUN with space reservation.

I used to have snapshots of the LUN in the volume, however they are all deleted. What I don't understand is why the volume reports 81% used spaced when there is only 1 LUN of 250 GB. My logic tells me 250 GB of 500 GB should be 50%. What is taking up space from 50% to 81%?

So when i go to my Hyper-v Node, start snapdrive and try to resize, I can't resize to more than 380 GB.

Seems very strange to me... Maybe it has something to do with this Fractional option...

Any help is very appreciated.

/Regards Martin
