OpenStack Stein : How to use Manila#22019/05/17 |
|
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. |
