Corosync looks at the netmask of the *interface* matching the bindnetaddr,
so if you've configured eth0 as (for example) 10.1.2.3/24, the appropriate
bindnetaddr is 10.1.2.0.  If you'd configured eth0 as a /8, the bindnetaddr
would need to be 10.0.0.0, and so forth.

Hope that helps to make everything even more confusing :)

Tim
