[Linux-cluster] Basic Active Active File Server

[Jason Fitzpatrick]

Hi..

I have tried both multicast and broadcast to no avail, as above I am
moving the systems to the same ESX to try and rule out the networking
end of things, I have not tried the tcpdump but was running wireshark
in an attempt to do the same as you recommended
