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


NFS versions

  • NFS was originally developed by Sun Microsystems: 
      
     NFSv2 released in 1985 
     NFSv3 released in 1995 
     NFSv4 released in 2003 for Sun and NetApp. Available in Linux now.
  • Detailed info about the NFS versions for Linux is available at http://nfs.sourceforge.net (the site looks away too outdated though).
  • NFS support should be enabled in Linux Kernel: 
    CONFIG_NFS_FS=m
CONFIG_NFS_V3=y
CONFIG_NFS_V4=y
CONFIG_NFS_DIRECTIO=y
CONFIG_NFSD=m
CONFIG_NFSD_V3=y
CONFIG_NFSD_V4=y
CONFIG_NFSD_TCP=y
  • Verify NFS support at run time: 
    lsmod | grep nfs
grep nfs /proc/filesystems
  • Verify what NFS version is currently running: 
    nfsstat
  • Check the NFS version currently being used by the client 
    mount
