[Crowbar] Deploying Swift on 3TB Disks

Thanks Greg,

We're seeing the problem deploying Swift on large storage disks using 
openstack-fred3.iso. Our drive setup that failed is:

/dev/sda   512GB SATA SSD
/dev/sdb   3TB SATA

We can deploy all the other OpenStack barclamps without incident. 
Further, we can deploy Swift when we replace the 3TB disks with smaller 
capacity drives.

I don't think we've updated the swift recipes to use GPT-based partitions, but I'm not completely sure.  This is part of the work to support larger the 2TB disks for Crowbar and its services.
