NFS mount fails with permission denied error because client not using IP allowed in export policy rule

Last Updated:

Applies to

  • ONTAP 9
  • NFS
  • IPv4 and IPv6


  • When try to mount the NFS on client, getting below error:
[root@linux ~]# mount -t nfs Ontap_IP:/NFS_IPV6 /mnt
mount.nfs: mount(2): Permission denied
  • Client fails to evaluate an export policy when multiple IP address are assigned.
  • IP "2620:118:8010:1096:250:56ff:fea6:fbb7" is allowed in clientmatch in export policy on Ontap:

cluster::*> export-policy rule show -vserver vs1 -policyname NFS_policy -instance
List of Client Match Hostnames, IP Addresses, Netgroups, or Domains: 2620:118:8010:1096:250:56ff:fea6:fbb7

  • However, there are multiple interfaces on client and has multiple IP addresses assigned:

Example for IPv6:

[root@linux ~]# ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet6 2620:118:8010:1096:250:56ff:fea6:a895  prefixlen 64  scopeid 0x0<global>

eth1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet6 2620:118:8010:1096:250:56ff:fea6:fbb7  prefixlen 64  scopeid 0x0<global>

Example for IPv4:

[root@xcpserver2 ~]# ifconfig
ens192: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 10.216.41.xx  netmask  broadcast
        inet6 fe80::af37:bb4:1eff:ebb  prefixlen 64  scopeid 0x20<link>

virbr0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        inet 192.168.122.xx  netmask  broadcast
        ether 52:54:00:42:dd:94  txqueuelen 1000  (Ethernet)
