RH436 – Red Hat High Availability Clustering
About Course
The Red Hat High Availability Clustering course offers in-depth training on creating, managing, and troubleshooting Red Hat Clustering and RHEL HA clusters. Learners will gain a foundational understanding of cluster technologies and storage solutions, focusing on the Pacemaker-based high-availability clusters. Through this course, students will learn to maintain cluster node membership, implement quorum decision-making, and configure fencing to safeguard cluster integrity. Additionally, the course covers the creation and management of resource groups, troubleshooting clusters, and handling complex resource groups with constraints. Two-node cluster issues, iSCSI initiators, multipath storage configurations, and the use of LVM in clustered environments are also discussed. The course provides practical knowledge on GFS2, eliminating single points of failure, and culminates in a comprehensive review where students set up high-availability services and storage, preparing them to ensure service availability and business continuity in enterprise environments.
