NFS Insecure Access To Secure Export

Description Cause

Workaround

User tries to access a secure export from an insecure port.

Secure export requirement means that the accessing clients must use a well-known port (below 1024), which usually means that they must be a root (uid=0) on the client.

•Identify the relevant export and verify that it is set as secure (requires secure client port).

•If the export must remain secure, see the NFS client documentation in order to issue the mount request from a well-known port (below 1024).

•If a secure export is not required (e.g., the network is not public), ensure that the export is insecure and retry accessing it.

NFS Mount Fails Due To Export Options

Description Cause

Workaround

This event is issued when NFS mount fails due to export options.

The export list filters client access by IP, network or netgroup, and screens the accessing client.

1.Verify the relevant export details. Write down all existing options so that you are able to revert to them.

2.Remove IP/client restrictions on the export and retry the mount.

3.If the mount succeeds, verify that the IP or domain is explicitly specified, or that it is part of the defined network or netgroups. Pay attention to pitfall scenarios, where the network netmask is not intuitive, for example, 192.175.255.254 is part of 192.168.0.0/12, but not of 192.168.0.0/16.

4.After the mount succeeds, adjust the original options accordingly.

NFS Mount Fails Due To Netgroup Failure

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.
