Ya, it doesn't seem right. all fileio img's are formatted NTFS. On a 3TB (disk3) unraid has a 1TB img, 1.9TB img, 537GB img and other shares. Disk3 says it still has 1.83TB free, it doesn't add up. When browsing disk3 all img file sizes are correct.
I didn't know you could basically mount an existing drive as iscsi, thats cool.
I have a 4TB drive I could set as block, but it wouldn't be parity protected. If I did that I might as well just mount it in my sons PC.
Just looking for any reason to use unraid.
