- Getting Help

• Check that the system's IP address, IP range, domain name or netgroup is in the
exports list.
If the appliance not responding due to a port mapper failure:
• Check the NAS cluster appliance status.
• Check the network connection by trying to NFS mount from some other system.
• Verify if other users experience the same problem.
If the appliance is not responding due to the program not registered, check if the port
mapper on your client is up.
If the issue is due to access denied:
• Get a list of the appliance exported file systems using the command:
showmount -e <FluidFS hostname>
• Check the system name or netgroup name is not in the user list for the file system.
• Check the file systems related to the NFS through the NAS cluster solution user
interface.
If the issue is due to the directory, check the spelling in your command and try to run
the mount command on both directories.
NFS Export Does Not Exist
Description Attempted to mount an export that does not exist.
Cause This failure is commonly caused by spelling mistakes on the client system or when
accessing the wrong server.
Workaround
1. Check the available exports on the NAS; verify that all the required exports exist.
2. On the problematic client, verify that the relevant export is available to this client:
3. % showmount -e <Server name/IP>
4. Export list for <Server name/IP>:
5. /abc 10.10.10.0
6. /xyz 10.10.10.0
7. If the export is available, review the export name spelling in the relevant mount
command on the client. It is recommended to copy paste the export name from
the showmount output to the mount command.
NFS File Access Denied
Description This event is issued when an NFS user does not have enough permissions for the file
on a NAS container.
Cause File ownership is UID/UNIX and the user is not privileged to access the file, or, file
ownership is SID/ACL and after translation to UID/UNIX the permissions do not allow
access to the file.
Workaround For native access (when CIFS user accesses SID/ACL file or NFS user accesses UID/
UNIX file) understanding the missing permission is standard.
If the access is non-native, translation rules come to effect and it is recommended
that you contact Dell Technical Support.
