尝试挂载NFS共享时收到错误"mount.nfs4：不允许执行操作"

适用场景

问题描述

• 无法挂载NFS共享、并出现以下错误：

[root@xxxxxx etc]# /sbin/mount.nfs4 -v svm1.de.db.com:/svm1_68953_1_006_nfs /usr/sap/testkrbp5 -o vers=4 sec=krb5p
mount.nfs4: timeout set for Mon Jun 10 15:45:06 2024
mount.nfs4: trying text-based options 'vers=4,addr=100.110.xx.xx,clientaddr=10.202.xx.xx'
mount.nfs4: mount(2): Operation not permitted
mount.nfs4: Operation not permitted

• 卷的安全模式为Unix。
• 用户正在使用挂载文件系统 vers=4, sec=krb5p。

• 卷中共享的导出策略允许使用NFSv4协议：

Cluster::> volume show NetAppvol -fields policy
vserver      volume              policy
--------------- ------------------------------- -------------------------------
svm       NetAppvol           NetApppolicy

Cluster::> vserver export-policy rule show -vserver svm -policyname NetApppolicy
