适用场景

  • ONTAP 9 及更高版本
  • NFS
  • 网络组

问题描述

  • 在导出策略中使用netgroup作为客户端匹配时、NFS挂载失败、客户端上显示以下错误:
mount.nfs: access denied by server while mounting nfs-server-name:/mount-point
 
  • 导出策略检查访问失败:
cdot_vsim_9_8::> check-access -vserver vs1 -volume vol1 -client-ip 10.x.2.x -authentication-method sys -protocol nfs3 -access-type read-write
  (vserver export-policy check-access)
                     Policy   Policy     Rule
Path              Policy    Owner    Owner Type  Index Access
----------------------------- ---------- --------- ---------- ------ ----------
/                default   vs1_root   volume      1 read
/vol1              policy-name   vol1    volume      0 denied
2 entries were displayed.
 
  • DNS反向查找失败:

cdot_vsim_9_8::*> vserver services name-service getxxbyyy gethostbyname -node node01 -vserver vs1 -hostname hostname.netapp.com

Error: command failed: Failed to resolve hostname.netapp.com. Reason: Unknown host.

  • EMS日志和mgwd日志将分别报告以下错误:

Sat Mar 12 10:34:52 +0000 [node01: kernel: protocol.exportCheckFailed:error]: Export access check failed on Vserver vs1 for client 10.x.2.x, trying to access volume vol1, having policy policy-name, via protocol nfs3. Reason: Access denied after export policy evaluation
