Thank you for being patient. I have made a new 13TB datastore and are moving around, and arranging the network so I can have 2gbit NIC teaming on my storage network. It is leading to unanticipated outages (I didn't think many of the changes would lead to downtime) but I think I had the firewall borked for the last 4 hours so...
This stuff should all be done in a day or so.
