When processing NFS export rules, an attempt to look up the DNS name for the specified host failed.

Administrator action

  1. Make sure that the DNS server includes an entry for the reported host name, and that non-Isilon hosts can resolve the host name.
  2. Check for misspellings and typographical errors in the cluster NFS configuration. Where possible, use a fully qualified domain name (FQDN) for every host in the NFS export rules. If you are not using a FQDN, make sure that each full domain name for the host is part of the DNS search path in the cluster configuration.

If the event persists, gather logs, and then contact EMC Isilon Technical Support for additional troubleshooting. For instructions, see Gathering cluster logs.
