This example shows to install Shared File Systems on the existing environment like follows.
For requirements on this example, it uses Cinder Storage as a backend,
so Configure Cinder and create a disk before it, refer to here. (it created a disk "disk01" with LVM backend on here)
Furthermore, it configured VLAN type of provider networking on this example.
