NFS Mount Fails Due To Netgroup Failure

If the access is non-native, translation rules come to
effect and it is recommended to contact Dell Technical
Support.
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 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.
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. Once the mount succeeds, adjust the original
options accordingly.
This event is issued when client fails to mount an NFS
export because the required netgroup information cannot
be attained.
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.
