OpenStack Zed : Manila 利用 (ローカルデバイス)2023/06/29

 
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。

[1] Storage ノードの設定です。
root@network:~#
apt -y install lvm2 nfs-kernel-server
# 空きデバイスに Manila 用ボリューム作成

root@network:~#
pvcreate /dev/sdc1

  Physical volume "/dev/sdc1" successfully created
root@network:~#
vgcreate manila-volumes /dev/sdc1

  Volume group "manila-volumes" successfully created
root@network:~#
vi /etc/manila/manila.conf
# [DEFAULT] セクション内の任意の場所へ追記

enabled_share_backends = lvm
# 最終行へ追記

[lvm]
share_backend_name = LVM
share_driver = manila.share.drivers.lvm.LVMShareDriver
driver_handles_share_servers = False
lvm_share_volume_group = manila-volumes
lvm_share_export_ips = $my_ip
root@network:~#
systemctl restart manila-share nfs-server

root@network:~#
systemctl enable manila-share nfs-server
[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。
