OpenStack Pike : How to use Manila#2
2017/09/07 |
|
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. On this example, create and use a Cinder storage [disk01] with 10G by LVM backend like here.
