I'm a greenhorn when it comes to clustering in RHEL/CentOS and recently setup an active/standby clustering using Apache & Heartbeat. It seems to be a good entry step into clustering however after testing it I was disappointed in that the resource manager does not start httpd on node2 if httpd on node1 is dead (only starts httpd on node2 if the heartbeat daemon on node1 is dead). Is there anyway to achieve this setup if not with Heartbeat with some sort of other HA solution?
You can write your own service test(s) that would trigger failover (or just restart the failed service...). Just do a 'service heartbeat stop' if you want the primary to hand off to the backup quickly.

Thank you all for your replies. In researching linux clustering more so I have discovered several other applications out there (primarily pacemaker, openais, and corosync). While I want to use pacemaker as my resource manager I am confused about openais & corosync. Is OpenAIS legacy and corosync the new current iteration?
Thanks again for your help!
