What You'll Learn:

🎓 Introduction to Clustering

• Understand the fundamentals of clustering, its types, and the advantages of clustering servers.
• Get familiar with key concepts like resource and resource groups, failover, fencing, shared storage, quorum, and cluster architecture.
• Set up a lab environment using KVM for a real-world application of what you learn.

Managing Cluster Nodes

• Master the operations of starting, stopping, and managing cluster services.
• Learn how to add or remove nodes from a cluster, handle standby and active nodes, and manage quorum effectively.

Creating High Availability Resources

• Dive into creating high-availability resources and understand how to manage them within the cluster.
• Configure a clustered Apache service as a practical example.

Troubleshooting High Availability Cluster

• Gain skills to troubleshoot common issues such as resource failures, network problems, and more.
• Learn to configure and inspect cluster logging for effective debugging.

Complex Resource Group

• Set up an Active/Passive NFS Resource Group and understand its configuration through a hands-on lab session.

Managing Constraints

• Understand the types of constraints like order, location, and colocation, and how to apply them in real scenarios with a guided lab session.

Two Node Cluster Issues

• Address challenges specific to two-node clusters, including handling node failures, split brain scenarios, and fence race issues.

Managing iSCSI Initiators

• Learn about the fundamentals of iSCSI, configure an iSCSI server, and explore various types of backing storage for a robust setup.
• Perform a lab session to create a block backstore from the targetcli shell.

Managing High Availability Logical Volumes (LVM)

• Explore the concepts of clustered LVM and HA-LVM, and perform a lab session to share a disk (lun) across all cluster nodes.

Clustered Logical Volumes

• Configure logical volumes in an active-active setup and manage them with tools like DLM and clvmd.

Global File System 2 (GFS2)

• Understand the concepts behind GFS2, create a GFS2 formatted Cluster File Systems, and learn to manage and repair it within the cluster.

💻 Practical Lab Sessions: Each module of this course includes practical lab sessions that allow you to apply what you've learned in a controlled environment. You'll gain the confidence and skills to implement high availability clustering solutions in real-world scenarios.
