RH436 Red Hat High Availability Clustering

Red Hat Certified System Administrator (RHCSA) exam (EX200) and associated courses or Red Hat Cerfitied Engineer (RHCE) exam (EX294) and associated courses.

Red Hat® High Availability Clustering (RH436) provides intensive, hands-on experience in deploying and managing shared storage and server clusters. In this course, you will learn how to provide highly available network services to a mission-critical enterprise environment through the deployment and management of shared storage and server clusters. Created for senior Linux system administrators, this course strongly emphasizes lab-based activities. You will set up a cluster of systems running the Pacemaker component of the Red Hat Enterprise Linux High-Availability Add-On, and deploy Linux-based services such as web servers and databases on that cluster. Cluster storage components from the Resilient Storage Add-On are also covered; installations and applications that require multiple cluster nodes can access the same storage simultaneously. This includes Logical Volume Manager (LVM) Shared Volume Groups, Red Hat Global File System 2 (GFS2), and Device-Mapper Multipath. This course is based on Red Hat Enterprise Linux 8.3

• Creating high availability clusters
• Create a basic high availability cluster.
• Managing cluster nodes and quorum

• Automating cluster and resource deployment
• Deploy a new high availability cluster and cluster resources using Ansible automation.
• Managing two-node clusters
• Operate two-node clusters while identifying and avoiding issues specific to a two-node cluster configuration.
• Accessing iSCSI storage
• Configure iSCSI initiators on your servers to access block-based storage devices provided by network storage arrays or Ceph storage clusters.
• Accessing storage devices resiliently
• Configure resilient access to storage devices that have multiple access paths.
• Configuring LVM in clusters
• Select, configure, and manage the correct LVM configuration for use in your cluster.
• Providing storage with the GFS2 cluster file system 
• Use the GFS2 cluster file system to simultaneously pProvide tightly coupled shared storage that can be accessed by multiple nodes.
• Eliminating single points of failure 
• Identify and eliminate single points of failure in your cluster to decrease risk and increase average service availability.
