OpenStack Train : How to use Manila#22019/10/28 |
|
This is How to use OpenStack Shared File System (Manila).
This example is based on the emvironment like follows.
For example, Configure Manila share to use a designed instance.

It needs to use Cinder storage for backends, so Configure Cinder service first.
(any backends are OK for Cinder)
|
| [2] | Configure Storage Node. |
