The Red Hat Certified Specialist in High Availability Clustering course provides advanced training on designing, managing, and troubleshooting Red Hat Clustering and high-availability (HA) clusters using Pacemaker. Participants will gain a comprehensive understanding of cluster technologies, storage solutions, and essential HA concepts.

The course covers:

• Cluster Node Management: Ensuring proper node membership and cluster integrity.
• Quorum Decision-Making: Implementing quorum to make decisions within the cluster.
• Fencing Configuration: Safeguarding cluster integrity by configuring fencing mechanisms.
• Resource Groups Management: Creating and managing resource groups, including handling complex constraints.
• Troubleshooting: Identifying and resolving cluster issues.
• Two-Node Cluster Issues: Addressing common challenges in two-node configurations.
• Storage Solutions: Configuring iSCSI initiators, multipath storage, and using Logical Volume Manager (LVM) in clustered environments.
• GFS2: Managing clustered file systems to eliminate single points of failure.

The course includes practical exercises and a comprehensive review to prepare learners for maintaining high-availability services and ensuring business continuity.

Course Prerequisites

To effectively participate in the Red Hat Certified Specialist in High Availability Clustering course, the following prerequisites are recommended:

• Basic Understanding of Linux Command Line: Comfort with terminal commands and Linux file system navigation.

Learning Objectives

After completing the Red Hat Certified Specialist in High Availability Clustering course, learners will be able to:

• Understand the fundamentals of cluster and storage technologies to form the base of high-availability solutions.
• Architect and implement Pacemaker-based high-availability clusters to ensure service continuity.
• Manage cluster node membership and implement quorum decision-making processes for cluster consistency.
• Configure fencing mechanisms to maintain cluster integrity and prevent “split-brain” scenarios.
• Create and manage resource groups to facilitate the high availability of critical services.
• Diagnose and troubleshoot common cluster issues to minimize downtime and service disruption.
• Use constraints to manage complex resource groups and maintain service dependencies within the cluster.
• Address specific challenges associated with two-node clusters, ensuring reliability even in minimal configurations.
• Manage iSCSI initiators and configure multipath storage for redundant access to shared resources.
• Implement and manage clustered Logical Volume Manager (LVM) and Global File System 2 (GFS2) to provide symmetric shared file systems.
• Identify and mitigate single points of failure, enhancing the overall availability of services across the cluster.
• Conduct a comprehensive review and hands-on setup of high-availability services and storage configurations as a capstone to the learning experience.
