Get an overview of storage and cluster technologies. Create high-availability clusters Review and create the architecture of Pacemaker-based high-availability clusters. Nodes and quorum Review cluster node membership and how quorum is used to control clusters. Fencing Understand fencing and fencing configuration. Resource groups Create and configure simple resource groups to provide high-availability services to clients.
Troubleshoot high-availability clusters Identify and troubleshoot cluster problems. Complex resource groups Control complex resource groups by using constraints. Two-node clusters Identify and work around two-node clusters issues. Create symmetric shared file systems. Eliminate single points of failure Eliminate single points of failure to increase service availability.
Comprehensive review Set up high-availability services and storage. Note: Course outline is subject to change with technology advances and as the nature of the underlying job evolves. For questions or confirmation on a specific objective or topic, please contact a training specialist. Outcomes Impact on the organization This course is intended to develop the skills needed to produce highly available, more resilient, mission critical applications, resulting in reduced downtime and easier hardware maintenance.
Red Hat has created this course in a way intended to benefit our customers, but each company and infrastructure is unique, and actual results or benefits may vary. Impact on the individual As a result of attending this course, students should be able to create, manage, and troubleshoot highly available network services and tightly-coupled cluster storage for business-critical applications.
Students should be able to demonstrate the following skills: Improve application uptime by using high availability clustering Manage storage in an high availability environment using iSCSI initiators, HA-LVM or CLVM as appropriate, and GFS2 cluster file systems Implement strategies to identify single points of failure in high availability clusters and eliminate them Recommended next exam or course.
