Troubleshooting 165NFS Mount Fails Due to Netgroup FailureDescription This event is issued when client fails to mount an NFS exportbecause the required netgroup information cannot be attained.Cause This error is usually the outcome of a communication errorbetween the NAS system and the NIS/LDAP server. It can be aresult of network issue, directory server overload, or a softwaremalfunction.Workaround Repeat the below process for each configured NIS server, each timeleaving just a single NIS used, starting with the problematic NISserver.1 Inspect the NIS/LDAP server logs and see if the reason for theerror is reported in the logs.2 Network test:a Try pinging the NAS from a client located in the same subnet asthe NIS/LDAP server.b Try pinging the NIS/LDAP server from a client located in thesame subnet as the NAS.If a packet loss is evident on one of the above, resolve the networkissues in the environment.3 Using a Linux client located in the same subnet as the NAS andconfigured to use the same directory server, query the netgroupdetails from the NIS/LDAP server using the relevant commands.Ensure that the reply is received in a timely manner (up to 3seconds).You can temporarily workaround the problem by removing thenetgroup restriction on the export and/or by defining an alternativedirectory server.Identify the relevant export and the options defined for whilefocusing on the netgroup definition. Document the used netgroupin order to restore it once the issue is solved and remove thenetgroup limitation.
