The LVS director does nothing (sorry) other than take an IP packet works
out which machine is next to send the data to. Changes the MAC address
in the Packet and passes it on.
The real servers believe they are talking directly to the client, they
know nothing about LVS and don't need to. All machines have the VIP on
them.
In your case, if I understand, you would not have the master of you
cluster as a server only the slaves. It is there to keep the slaves up
to date.
I strongly suggest you go to www.ultramonkey.org and read the how to's
and explanations on there.
