After updating the NFS-server to RHEL-5.9, ls or ls with a wildcard is not displaying the files on NFS share

Issue

• Files on NFS share are not getting displayed while executing ls or ls with wildcard, but the same is displaying ls with exact file name:

  • on the NFS-client in the mountpoint:

  user@nfs-client $ ls -x1 | wc -l
  3
  

  • on the NFS-server in the exported directory:

  user@nfs-server $ ls -x1 | wc -l
  347
  

• On RHEL 6 NFS client, multiple . & .. entries getting listed when looking at them using ls? These direcories not there on NFS server:

# ls -il /<NFS_Mounted_Dir>
