NFS 服务器拒绝挂载请求

无法将 NFS 卷挂载到 ESXI 主机或 Unix，收到权限被拒绝错误：
- Unix： [root@xxxx ~]# mount /temp/wes_test/mount.nfs: access denied by server while mountingxx.xx.xx:/test
- ESXI：Operation failed, diagnostics report: Mount failed: Unable to complete Sysinfo operation. Please see the VMkernel log file for more details.: The NFS server denied the mount request
“check-access”命令输出显示对 vserver vsvm 上具有“default”导出策略的根卷的访问被拒绝：
- ::> check-access -vserver vsvm -volume PROD_NFS -client-ip 10.1.2.3 -authentication-method sys -protocol nfs3 -access-type read-write
  
  (vserver export-policy check-access)

进一步调查显示，vserver vsvm 默认策略没有规则
