The Corosync configuration would be the same as one in a single location, it would be up to you to get the multicast routing right. For unicast, you'll have to install Corosync 1.3.0 or later; then check the corosync.conf man page for "udpu". However, really, don't do this. Corosync, just like all other cluster communications layers, is very sensitive to network latencies, and unless you work for someone like the CIA or CERN or NASA, or a large backbone provider, you're not going to have access to multiple physical locations connected with near-LAN latency. Hope this helps, Florian -- Need help with Corosync? http://www.hastexo.com/knowledge/corosync _______________________________________________ discuss mailing list discuss@xxxxxxxxxxxx http://lists.corosync.org/mailman/listinfo/discuss
