OpenStack Queens : Manila 利用方法#22018/03/11 |
|
OpenStack Shared File System（Manila）による共有の設定です。
当例では以下のような環境を例に Manila をインストールして設定しています。
例として、専用のインスタンスを利用した NFS 共有を設定します。

バックエンドに Cinder ストレージを利用するため、事前に設定しておきます。(Cinder のバックエンドは何でも OK)

| [3] | Manila のサービスイメージをダウンロードして、Glance に登録しておきます。また Manilaサービス用のセキィリティグループも作成しておきます。作業場所はどこでも良いですが当例では Control ノード上で行います。 |
