環境

  • ONTAP 9.10.1以前
  • 4ノードクラスタ

問題

4ノードクラスタの特定のケースでは、次の処理が行われます。

  • ノードとそのHAパートナーが消去されたか、先に分離せずに削除された
  • 残りの2つのノードのどちらにもイプシロンが設定されていないと、クラスタクォーラムが失われることがある
  • その後、 ノードを分離するように設定すると、 次のエラーが表示されて失敗します。

::*> cluster unjoin -node Cluster-node-3 -force
 
Warning: This command will forcibly unjoin node "Cluster-node-3" from the
         cluster. You must unjoin the failover partner as well. This will
         permanently remove from the cluster any volumes that remain on that
         node and any logical interfaces with that node as the home-node.
         Contact support for additional guidance.

       after excluding "Cluster-node-3". Please repair the unhealthy nodes, and
