NFS Insecure Access To Secure Export Description Cause Workaround 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. 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. Once the mount succeeds, adjust the original options accordingly. NFS Mount Fails Due To Netgroup Failure Description Cause 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. 78

NFS Insecure Access To Secure Export
Description
User tries to access a secure export from an insecure
port.
Cause
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.
Workaround
•
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.
