But, corosync can run with unicast aswell right? I'm deploying it on AWS (Amazon Web Services) and they don't allow multicast.<br><br><div class="gmail_quote">2012/10/2 Lars Marowsky-Bree <span dir="ltr"><<a href="mailto:lmb@suse.com" target="_blank">lmb@suse.com</a>></span><br>

</div>As long as it's corosync with multicast (and the nodes still being able<br>
to communicate on the mcastaddr), it ought to be possible there.<br>
<br>
Mind, it isn't necessarily a great idea, but it should work. I'm not<br>
sure if statically assigned nodeids are going to be more reliable or<br>
not though.<br>
