Volume Size Not Reporting Correctly

[russdyer]

I am running version 8.0.2 and noticed something weird. I have 4 2TB hard drives and when I started FreeNAS correctly reported about 5.4TB "size"/"available" in the "Storage" tab. I created datasets and loaded up some of the space and noticed that the "available" and "total" changes as I load information on the volume so now it is showing 3.3TB under both "available" and "total". "Total" should ALWAYS report "5.4TB" and not change and the "available" should subtract, but this doesn't happen. Both "total" and "available" change so I cannot tell how much space is actually still available.
