RH436 - Red Hat High Availability Clustering Course Overview

Certainly! Here are the minimum required prerequisites for successfully undertaking training in the Red Hat High Availability Clustering course, formatted for inclusion in the FAQ section of Koenig Solutions' website:

• Basic understanding of Linux command line: Students should be comfortable using a terminal, entering commands, and navigating the Linux file system.
• Fundamental knowledge of Linux administration: Familiarity with general system administration tasks such as managing users, groups, permissions, and software packages is expected.
• Experience with Red Hat Enterprise Linux (RHEL): Students should have prior experience or training equivalent to the Red Hat System Administration I (RH124) and II (RH134) courses.
• Familiarity with text editors: An understanding of how to use text editors like vi or nano to edit configuration files is necessary.
• Networking knowledge: Basic networking concepts such as IP addressing, hostname resolution, and firewalls should be understood.
• Logical Volume Manager (LVM): An awareness of disk management and LVM concepts will be beneficial.
• Concept of storage devices: Students should know about different types of storage (e.g., local, network-attached storage, storage area networks).

These prerequisites ensure that learners have a solid foundation upon which to build their high availability clustering skills using Red Hat technologies.

Learning Objectives - What you will Learn in this Red Hat High Availability Clustering?

Introduction to the Course Learning Outcomes and Concepts Covered:

The Red Hat High Availability Clustering course is designed to teach participants how to implement and manage robust clusters for mission-critical services using Red Hat technologies.

Learning Objectives and Outcomes:

• 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.
