由于 CIFS 操作超时，无法访问 CIFS 共享

集群模式 Data ONTAP

问题

无法访问 CIFS 共享，因为 CIFS 操作超时

无法访问 CIFS 共享。尝试访问 CIFS 共享的客户端会报告延迟，然后显示以下错误消息：
Windows cannot access \share

EMS/ 控制台日志显示以下错误消息：
Nblade.CifsOperationTimedOut: Detected a timed out CIFS operation. SMB command code for this operation: 1 Number of times this command was suspended: 3 Number of times this command was restarted: 0

secd logs 将显示以下错误消息：
secd.cifsAuth.problem: vserver (vs_nas) General CIFS authentication problem. Error: User authentication procedure failed

[ 3] User 'DOMAIN\user' authenticated using NTLMv2 security
[ 5006] Windows user 'DOMAIN\user' mapped to UNIX user 'pcuser'
[ 5006] Entry found for group-membership: pcuser using source: FILES
[ 9335] No servers available for NIS, vserver: 3, domain: .

2. 对于远程 LIF 流量

，使用集群模式 Data ONTAP 的 FAS 25xx 上的高协议延迟用户报告访问 FAS 25xx 系列和集群模式 Data ONTAP 上集群模式 ONTAP 上托管的数据时协议延迟较高。

系统具有用于集群间端口的 QLogic NIC 卡。

AUPS 中可以报告类似于以下内容的 EMS 日志：
NwkThd_02: Nblade.dBladeNoResponse:warning]: Gave up retrying a file operation due to no response from the specified node. UUID of the node where data is located is fa000834-a355-11e4-87bc-5f5978ef59aa; the protocol for the operation is NFS.

可能还会报告类似以下内容的错误消息：
[Nblade.JunctionRootLookup2:warning] Junction root lookup of a volume in Vserver 5 with MSID 2147484692 has failed for reason "CSM_TIMEOUT"

[Nblade.CifsOperationTimedOut:error] Detected a timed out CIFS operation. SMB command code for this operation: 5 Number of times this command was suspended: 2 Number of times this command was restarted: 0 Last CSM error during this operation: CSM_TIMEOUT Last SpinNp error during this operation: SPINNP_NO_FO_ERROR Client IP address: xxx.xxx.xxx.xxx Local IP address: xxx.xxx.xxx.xxx Target Vserver ID: 5 Target disk's DSID: 0

2A  FAS25xx 采用集群模式 Data ONTAP 、可实现远程 LIF 流量的高协议延迟

3. 在此操作

期间， Nblade.CifsOperationTimedOut 与上次 SpinNp 错误： SPINNP_ERR_delay due to disconnected FPolicy server clients Experience access issues （ timeouts ） on specific operation.

4. Nblade.CifsOperationTimedOut ：检测到 CIFS 操作超时

事件日志显示以下内容：
==
Nblade.CifsOperationTimedOut: Detected a timed out CIFS operation. SMB command code for this operation: 5 Number of times this command was suspended: 3994 Number of times this command was restarted: 0 Last CSM error during this operation: CSM_OK Remote blade UUID: 00000000000000000000000000000000 Is QoS enabled: QoS_disabled Last SpinNp error during this operation: SPINNP_NO_FO_ERROR Client IP address: 10.10.10.10 Local IP address: 192.168.10.10 Target Vserver ID: 3 Target disk's DSID: 3
