there are a couple of dead links here. I didn't see how to raise an issue about it. I hope that the comment section is a good place:
- Step-by-step clustering guides from linode.com
- Pacemaker project statistics
- MySQL with Pacemaker
- RabbitMQ - High Availability with Pacemaker and DRBD
- Making OpenNMS highly available with Pacemaker
- Nice walkthrough of Xen+DRBD on Debian (server does not reply)
