HA and cluster concepts
High Availability, downtime, redundancy, single points of failure, what is clustering? Cluster components, Cluster architectures, performance, shared file systems, RAID issues, making applications highly available.

Preparing Linux for clustering
Linux hardware components, creating shared filesystems. Hands on: Installing Linux for clustering.

Heartbeat
What is heartbeat? Heartbeat versions, obtaining heartbeat, installing heartbeat. Hands on: Installing Heartbeat.

Heartbeat configuration
ha.cf, Configuring the primary system, configuring the secondary system. Hands on: Creating clusters.

Configuring resources
Resource types, Resource agents, cib.xml, resource groups, constraints. Data access architectures. IO fencing, STONITH. Hands on: Resource configuration.

How heartbeat works
Membership, heartbeat messages, authentication. Time. Log files, crm_verify. Hands on: Troubleshooting.

Cluster management
Failover methods, failover testing, ipfail, DRBD, verifying shared resources. Hands on: Managing clusters, failover analysis.

Highly available network resources
DNS, DHCP, Apache, others. Configuring Heartbeat to control the applications. Hands on: Apache and clusters
