環境

  • ONTAP 9
  • NFSv3 / マウントプロトコル
  • FlexCache ボリューム

問題

  • Linux 上で「 mount.nfs : Connection timed out 」が表示されるか、同等のマウントエラーが記録されます(実際のエラーはクライアントプラットフォームに固有です)。

mount -t nfs -s -o ro,intr,retrans=10,timeo=600,nfsvers=3,hard,rsize=32768,wsize=32768,tcp,noacl,port=2049,nocto sgh-cdot01-corp01:/vol/Test_FC/dester/centos7/x8675/dester_2-pic /mnt -vvv

  • FlexCache ボリュームから特定のパスをマウントしようとすると、マウント処理がタイムアウトします。
  • パケットトレース NULLMNTは、マウントのためのコールが応答されたことを示していますが、コールは応答されません。クライアントは要求の RPC 再送信を実行しますが、応答は得られません(次の Wireshark と tShark の出力例を参照)。
