OpenStack Rocky : Manila 利用方法#12018/09/18 |
|
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、Storage ノードのローカルブロックデバイスを
LVM バックエンドの共有ストレージとして設定し、インスタンスから利用できるようにします。
よって、前提として Storage ノードに空きブロックデバイスがある必要があります。

| [2] | デフォルトの共有タイプを作成します。作業は、どこでもよいですが、当例ではコントロールノード上で行います。 |
