Data Domain: NFS mount: ls results in error: reading directory '.': Stale file handle total 0

Clients can successfully mount to NFS export (Example: /ddvar) 

Running the command: "ls" results in the message:
Stale file handle 

Clients can cd to directories under /ddvar/ like releases or log and then ls returns results. 
    "cd releases" or "cd log" then "ls" succeeds.

One potential cause for this behavior is a broken symbolic link.

The steps below help you confirm if this behavior is due to a broken symbolic link within the NFS export (Example: /ddvar)

1) Enter SE mode and run ls to the export path. Example:

ddvar #se ls -al /ddr/var/

NOTE:  ddvar is a special path. /ddvar is internally translated to /ddr/var and must be used as /ddr/var when using internal commands.
2) Look for symbolic links:  (Example below, note the "l" on the left-most character and also the "->"   These indicate that you have a symbolic link.)

lrwxrwxrwx 1 root    root    36    Nov 27    2020    link_to_new_rpmfile.rpm -> /ddr/var/ext/link_to_new_rpmfile.rpm

3) If you find a suspect link, check that the original file exists.

#se ls -al /ddr/var/ext/link_to_new_rpmfile.rpm
ls: cannot access /ddr/var/ext/link_to_new_rpmfile.rpm

  4) If you get an error that the file does not exist, this confirms that you have a broken symbolic link. It must be corrected, or the link must be deleted.

5) To correct a broken link, open a case with Dell Support. Supply the evidence already collected and mention this KB article.
