環境

  • ONTAP 9
  • FlexCache
  • CIFS / SMB

問題

  • CIFS / SMBクライアントではスペースがないためにFlexCacheボリュームファイルに大容量ファイルを書き込むが、NFSでは同じ処理が成功する
  • 障害が発生すると、CIFS処理タイムアウト(Nblade_CifsOperationTimedOut_1 または Nblade.CifsOperationTimedOut)のEMSイベントがlastSpinNpErrorとしてSPINNP_ERR_RETRYとともに表示されます。
    • Wed Dec 14 19:48:04 -0500 [CLUSTER-01: kernel: Nblade_CifsOperationTimedOut_1:error]: params: {'remoteBladeID': 'abcdefgh-jklm-nopq-rstu-vwxyz1234567 (CLUSTER-01)', 'cmdRestartCnt': '0', 'vserverId': '3', 'commandName': 'SMB2_COM_QUERY_DIRECTORY', 'isQosEnabled': 'QoS_disabled', 'lastSpinNpError': 'SPINNP_ERR_RETRY', 'localIpAddress': '10.1.1.100', 'lastCsmError': 'CSM_OK', 'clientIpAddress': '10.100.2.200', 'vserverName': 'svm1', 'suspensionCnt': '80', 'dsId': '1234'}
  • その時点でのSKTRACEにスペースエラーが表示されない
