Here is a word of advice, since its covered multiple times in these forums:
When creating a new thread and you have an issue, GIVE ALL THE INFORMATION YOU CAN ABOUT YOUR SETUP. This back and forth shit is time-wasting and worthless. Lay out your setup/config, end goal and issue. Every post is you adding some other little tidbit of information that makes this a waste of time.
"as well" meaning, you have issues/requests/questions AND you are doing something completely unsupported, well-documented to be troublesome, and against the recommendations of the pros around here....
As I said, you should check out OMV, as it should do EXACTLY what you want. If you are looking to REQUEST that these features be ADDED to future FreeNAS builds, then you should file it as a bug/feature request, and not complain on the forum about how it doesnt do what YOU want it to do.
