freenas 9.3 newbie

[ify]

How come freenas 9.3 creates 2 datasets when creating a volume?

I have 6 3tb hard drives raidz and it only shows 16 available and on the second dataset it shows 12.5 tb available. i believe im loosing some storage some where?

Dont eat my head off cyberjock. im just really new to this...

It's always done this but didn't start displaying it until 9.3. See http://doc.freenas.org/9.3/freenas_storage.html#view-volumes for an example.
