OpenStack Newton : Manila 利用方法#2
2016/10/31
 
OpenStack Shared File System(Manila)による共有の設定です。
ここでは以下のような環境に Manila をインストールして設定しています。
例として、当例では、専用のインスタンスを利用した NFS 共有を設定します。
前提として、バックエンドに Cinder ストレージを利用します。
ここでは例として LVM バックエンドで disk01 というストレージを 10G で作成しています
また、ネットワークは Open vSwitch バックエンドの VLAN タイプのプロバイダーネットワークを構成しています
