Detailed Course Outline
Creating high availability clusters
Create a basic high availability cluster.
Managing cluster nodes and quorum
Manage node membership in the cluster and describe how it impacts cluster operation.
Isolating malfunctioning cluster nodes
Isolate unresponsive cluster nodes to protect data and recover services and resources after a failure.
Creating and configuring resources
Create basic resources and resource groups to provide highly available services.
Troubleshooting high availability clusters
Identify, diagnose, and fix cluster issues.
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.
