The first of a new series of step-by-step guides for Pacemaker.

This installment covers installation, the creation of an active/passive cluster and its conversion to active/active.

Technologies used include:

  • Fedora 11 as the host operating system
  • OpenAIS to provide messaging and membership services,
  • Pacemaker to perform resource management,
  • DRBD as a cost-effective alternative to shared storage,
  • OCFS2 as the cluster filesystem (in active/active mode)
  • The crm shell for displaying the configuration and making changes
  • Apache as the example service.

The PDF is available from our Documentation page or directly via

Future guides are anticipated to include MySQL, mail servers and asymmetrical clusters. Feedback and suggestions for additional topics are welcome.
