  • Management Gateway Daemon(MGWD)はオフラインになり、約(<20)秒で再びオンラインになります

注:  MGWDはどのサービスを処理しますか?

Mgwdは、クラスタ内のすべてのノードで実行されるプロセスで、次のことを行います。

  • Clustershellコマンドラインアクセスを提供
  • 外部ZAPIおよびREST APIのノードへの呼び出しを処理
  • 認証されたSystemshellへのアクセスを管理
  • コアファイルは自動的に生成されず、クラスタシェルからこのコマンドを実行しても確認されません: system node coredump show
