      How reproducible:

       Tried Mounting the nfs server on the node and it worked but tried same from the pod having privileged scc

      Steps to Reproduce:

          1. Run a custom application 
           ~~~
            oc new-app <image-name>
           ~~~
          2.Create a service account and add scc privileged to it
            ~~~
             oc create sa < sa-name>
      
             oc adm policy add-scc-to-user privileged -z <sa name>
            ~~~
          3. Set the Service Account to the deployment created
           ~~~
             oc set sa deployment/<deployment-name> <sa-name>
           ~~~

       

          4. Run the mount command inside the pod
            ~~~    
             oc rsh <pod-name>
             
             mount -t nfs 10.0.x.x:/nfs/exports/myshare /nfs/import/ 
            ~~~
          5. Run the same command inside the node it will work 
             ~~~
              oc debug node/<node-name>
      
              mount -t nfs 10.0.x.x:/nfs/exports/myshare /nfs/import/ 
            ~~~

       

       

      Actual results:

         ~~~
         $ mount -t nfs4 10.0.88.72:/nfs/exports/myshare /nfs/import/
          
            mount: /nfs/import: permission denied.
         ~~~

      Expected results:

          It should get mount and visible in df -h output 
           ~~~
           10.0.x.x:/nfs/exports/myshare   19G  3.2G   16G  17% /tmp
