About this course
High availability is the feature most teams trust without fully understanding. This one-day deep dive demystifies the HA stack — how the resource manager makes decisions, what fencing really protects against, and how to design groups and failure domains that match your actual risk.
The final lab is deliberately destructive: we kill nodes, isolate networks and cut storage, then watch the cluster recover. You leave knowing exactly what your own HA policy will and will not survive.
Agenda
- HA stack architecture — The resource manager, LRM and CRM components.
- Designing HA groups & priorities — Grouping guests, setting priorities and restricting nodes.
- Fencing devices & watchdog — Why fencing exists and how to configure a reliable watchdog.
- Failure scenarios & recovery — Node, network and storage failure behaviour.
- Tuning migrate/relocate policies — Recovery policy, bandwidth and scheduling trade-offs.
- HA lab: kill the node — Controlled destruction and observation of failover.
