NFS Share Permission Denied When Accessing via DNS Load Balancer
Applies to
- ONTAP 9
- NFS/CIFS
- DNS Load Balancer
Issue
- Linux servers intermittently receive “Permission denied” errors when accessing NFS shares using a DNS load balancer (FQDN). The error may appear in application logs or during automated job execution.
- Mounting the NFS share directly to the ONTAP Data LIF IP works without issue.
