[Samba] CTDB Setup Basics: Virtual IPs

Hello everyone,

the docs @ https://wiki.samba.org/index.php/Basic_CTDB_configuration talk
about the nodes file which should contain IPs from "private non-routeable
subnet". What is that exactly?

My 3 gluster nodes get their IPs from DHCP and those are, and These are the ones I should place inside the
nodes file right? I guess so, because the cluster is running.

Now it gets a bit confusing for me. The public_addresses file from
https://wiki.samba.org/index.php/Adding_public_IP_addresses should contain
public IP addresses which are used by clients to connect to the Samba
shares later on. However on my gluster nodes I only have one NIC which is
represented by eth0.

1. How can and another public IP be assigned to the same nic
2. If I choose for the public IP then how do I tell my DHCP
server not to assign this address to other nodes?
3. Do I assign 1 or addresses to 3 gluster nodes and why?

This is a small home network. How do I set it up correctly for CTDB? My
clients are Macs, Windows PCs and CentOS servers.
