NFS versions

  • NFS was originally developed by Sun Microsystems: 
      
     NFSv2 released in 1985 (no longer supported on Ubuntu and RedHat)
     NFSv3 released in 1995
     NFSv4 released in 2003
  • Detailed info about the NFS versions for Linux is available at http://nfs.sourceforge.net (the site looks away too outdated though).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_V2=m
CONFIG_NFS_V3=m
CONFIG_NFS_V3_ACL=y
CONFIG_NFS_V4=m
CONFIG_NFS_V4_1=y
CONFIG_NFS_V4_2=y
CONFIG_NFS_V4_1_IMPLEMENTATION_ID_DOMAIN="kernel.org"
CONFIG_NFS_V4_1_MIGRATION=y
CONFIG_NFS_V4_SECURITY_LABEL=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
