Solution Verified - Updated -


  • NFS share is not mounting correctly at boot time as specified in fstab file.
  • Unable to mount nfs share at boot time on Red Hat Enterprise Linux 5.5.
  • NFS/SMBFS mounts do not mount when the system boots up, however, running the following command after boot works to mount the NFS or SMBFS shares:

    # mount -a 

    Need to know why NFS mounts didn't mount after reboot.
