環境

  • ONTAP 9
  • Varonis FPolicy
  • Commvault FPolicy

問題

  • FPolicy解決策の実装後にCIFSクライアントのレイテンシが高くなる
  • CIFS共有へのアクセス時に断続的な問題が発生する
  • EMSログにmaxPendingReqとserver disconnectメッセージが表示される:
    Mon Apr 2 18:00:40 +0000 [CLUSTER-01: fpolicy: fpolicy.server.maxPendingReq:info]: Maximum outstanding requests for the FPolicy server "10.1.2.4" has reached.
    Mon Apr 2 18:00:41 +0000 [CLUSTER-01: fpolicy: fpolicy.server.disconnect:error]: Connection to the FPolicyserver "10.1.2.4" of policy "fpolicy1" is broken for Vserver CLUSTER_SVM_CIFS ( reason: "Server progress timeout is hit." )
  • 影響を受けるポリシーは、外部エンジンタイプが同期であることを示しています
