There are two options for configuring cluster resources:
The first is very simple to configure because it doesn't do very much
- Clusters are limited to 2 nodes
- No detection of resource-level failures
- Resources organized into independent groups with a strictly linear start/stop order
Traditionally Pacemaker has been more complex to configure, however it now comes with a nice command line tool that hides the XML scaffolding that frightened many potential users.
To enable Pacemaker, shut down all the nodes and adding the following to /etc/ha.d/ha.cf
Then sit down with a warm drink and read the Pacemaker documentation.
