A customer reports that a Linux system is unable to access a required NFS export on an ONTAP SVM named “svm01-02”. This is an important server in their NIS environment and users are unable to log in. Referring to the logs, they see several notifications of the message shown below.
exports.netgroup.dnsNoPtrRec: IP address 192.168.1.13″ does not have a reverse mapping for its corresponding hostname in the configured name servers when evaluating the export-policy rules for netgroup “linux_1” on Vserver “svm01-
02″.”
In this scenario, what is causing the problem?
A. The export policy has the wrong netgroups defined.
B. The DNS server does not have the relevant mapping from the IP address to the hostname.
C. The ns-switch sources are set to files,dns instead of hosts,dns.
D. The netgroup definition in NIS is missing the 192.168.1.13 IP address.
