  Doplnim myslienku - zabudol som totiz doplnit, ze gmirror tam dam.

  Schema ggate nfs exportu
  ========================
  
           /localdisk zo server1 \
  server1                         => gmirror server1 \
           /ggate zo server2     /          |         \
                                            |          \
                                        heartbeat       => NFS export
                                            |          /
           /localdisk zo server2 \          |         /
  server2                         => gmirror server2 /
           /ggate zo server1     /
  

  Dufam, ze nakres nic nezmrsilo, a ze je to aspon na papieri
  realizovatelne :).
