问题描述

尝试挂载NFS导出时、NFS报告以下错误：

mount.nfs: Connection timed out

EMS日志包含：

[node1: ypbind: nis.server.not.available:error]: None of the NIS servers configured for SVM 'svm1' can be contacted.

从ONTAP命令行执行导出策略检查失败：

Example

::> vserver export-policy check-access -vserver vserver_name -volume vol_name -client-ip XX.XX.33.20 -authentication-method sys -protocol nfs3 -access-type read-write

Error:  show failed: Failed to check exports for Vserver "svm1". The command returned an error when evaluating an
         entry in the client match "@netgroup1" for rule at index "1" in export policy "policy1". Error code:         7223(export check for netgroup returned a transient error). The problem appears to be in the name         service configuration for the client match specified in the rule. Wait for a few seconds, and then try the         command again. If this error persists, contact technical support personnel for assistance.
