Network File System (NFS)
Linux for Engineering and IT Applications


Standard mount 





  • Mount point (directory) needs to be created before mounting
    •  
an NFS file system. For example,

    mkdir /mnt/nfs

    


  • The NFS directory can be mounted manually:
    • 

    mount -t nfs server_name:/exported_dir  /mnt/nfs

    
then run  df -h  to see if it has been succesfully mounted.


    

  • Manual mounting with options other than defaults:

    mount -t nfs -o rw, hard, rsize=2048, wsize=2048 server_name:/exported_dir  /mnt/nfs

    


  •  Most Common Options (described in NFS-HOWTO)

    rw
ro
hard
soft
intr
rsize
wsize

    


  • To unmount a directory, you can run command

    umount /mnt/nfs

    


  •  The NFS  directories can be mounted at bootup time if they are
    •  
included in /etc/fstab file: 

    # file system     mount point  fstype   flags           dump  fsck       
server1:/home     /mnt/home     nfs    rw,intr,hard     0     0
server2:/users    /mnt/users    nfs     defaults        0     0

    


  • When /etc/fstab has been modified, you can run
    •  

    mount -a

    
or reboot the machine
