I was able to figure out what the issue was.  At the bottom of the NFS export configuration is settings for security that had kerberos selected and not UNIX.  I unselected all the kerberos and selected UNIX.  All Joy!
Community,   I am having a hard time getting a NFS export to mount from a cluster with OneFS 8.0.0.5 installed.  The stipulation was that the export has to be READ-ONLY and "No root squash."  Here is what this looks like for how I have this configured on the cluster.                   ID: 4                     Zone: System                    Paths: /ifs/data              Description: Clarity Now POC - READ-ONLY; No root squash                  Clients: -             Root Clients: -        Read Only Clients: -       Read Write Clients: -                 All Dirs: No               Block Size: 8.0k             Can Set Time: Yes         Case Insensitive: No          Case Preserving: Yes         Chown Restricted: No      Commit Asynchronous: No  Directory Transfer Size: 128.0k                 Encoding: DEFAULT                 Link Max: 32767           Map Lookup UID: No                Map Retry: Yes                 Map Root                      Enabled: True                         User: root                Primary Group: -             Secondary Groups: -             Map Non Root                      Enabled: False                         User: nobody                Primary Group: -             Secondary Groups: -              Map Failure                      Enabled: False                         User: nobody                Primary Group: -             Secondary Groups: -                 Map Full: Yes            Max File Size: 8192.00000P            Name Max Size: 255              No Truncate: No                Read Only: Yes              Readdirplus: Yes     Readdirplus Prefetch: 10    Return 32Bit File Ids: No   Read Transfer Max Size: 1.00M   Read Transfer Multiple: 512       Read Transfer Size: 128.0k            Security Type: krb5, krb5i, krb5p     Setattr Asynchronous: No                 Snapshot: -                 Symlinks: Yes               Time Delta: 1.0 ns    Write Datasync Action: datasync     Write Datasync Reply: datasync    Write Filesync Action: filesync     Write Filesync Reply: filesync    Write Unstable Action: unstable     Write Unstable Reply: unstable  Write Transfer Max Size: 1.00M  Write Transfer Multiple: 512      Write Transfer Size: 512.0k     Using the following command on the remote server I could not get the filesystem to mount.   $ sudo mount first-nfs.[DOMAIN].org:/ifs/data /mnt/firstCluster/ mount.nfs: an incorrect mount option was specified   What FSTAB looks like on the remote server:  # # /etc/fstab # Created by anaconda on Thu Nov  9 11:26:29 2017 # # Accessible filesystems, by reference, are maintained under '/dev/disk' # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info # /dev/mapper/cl-root     /                       xfs     defaults        0 0 UUID=7abb8c81-867c-419a-b4ab-40836f11ec99 /boot                   xfs     defaults        0 0 /dev/mapper/cl-swap     swap                    swap    defaults        0 0 First-nfs.[DOMAIN].org:/ifs/data /mnt/FirstCluster nfs ro 0 0 Second.[DOMAIN].org:/ifs/data /mnt/SecondCluster nfs ro 0 0  Please let me know what I could be doing wrong.
