Currently we choose the largest available disk as the data disk, however this may be too small to be useful. This patch checks disqualifies disks that are smaller than the minimum. It also sets the minimum to the proper value of 60GB free on the root disk or 60GB available on the designated secondary disk. The previous check was 60GB on root and 80GB on the secondary disk which is not the intented check as noted in the documentation. Change-Id: Id225dc55068e1eed2e19e1e27b0f626163f03db2
