Dell FluidFS NAS Solutions Administrator's Guide

Description

This event is issued when client fails to mount an NFS export because the required netgroup information cannot be attained.

Cause

This error is usually the outcome of a communication error between the NAS system and the NIS/LDAP server. It can be a result of network issue, directory server overload, or a software malfunction.

Workaround

Repeat the following process for each configured NIS server, each time leaving just a single NIS used, starting with the problematic NIS server:

1. Inspect the NIS/LDAP server logs and see if the reason for the error is reported in the logs.
2. Complete a network test by pinging the NAS from a client located in the same subnet as the NIS/LDAP server.
3. Ping the NIS/LDAP server from a client located in the same subnet as the NAS.
4. If a packet loss is evident on one of the above, resolve the network issues in the environment.
5. Using a Linux client located in the same subnet as the NAS and configured to use the same directory server, query the netgroup details from the NIS/LDAP server using the relevant commands. Ensure that the reply is received in a timely manner (up to 3 seconds).

You can temporarily workaround the problem by removing the netgroup restriction on the export and/or by defining an alternative directory server.

Identify the relevant export and the options defined for it, while focusing on the netgroup definition. Document the used netgroup in order to restore it after the issue is solved and remove the netgroup limitation.
