OpenStack Newton : How to use Manila#22016/10/31 |
|
This is How to use OpenStack Shared File System (Manila).
This example shows to install Manila on the existing environment like follows.
For example, Configure Manila share to use a designed instance.
It needs to use Cinder storage for backends, so Configure Cinder and create a block storage first. Furthermore, this example is based on the environment which Open vSwitch based VLAN network by Neutron is configured.
