This course helps you to understand high availability clustering by providing a strong concept and hands-on experience with Pacemaker and Corosync components of Red Hat / CentOS Enterprise High Availability Cluster. Lab Design : KVM based lab setup in this course module. Course Content: Introduction What is clustering & cluster types? Advantages of Clustering Servers Concepts and techniques Resource and resource groups Failover, Fencing, Shared Storage, Quorum Cluster Architecture Lab Setup using KVM Environment Configuring a Basic Cluster Configuring a fencing agent using KVM host mahcine Troubleshooting fencing device Managing Cluster Nodes Starting & Stopping Cluster Services Enabling & Disabling the Cluster Services Adding & Removing A Cluster Node The Standby & unstandby Nodes Quorum Operations Lab Session on quorum Managing Quorum Calculations Cluster Setup Switches 1) wait_for_all 2) auto_tie_breaker Creating and Configuring Resources Create and configure high-availability resources. Creating a clustered Apache service Managing Resources Troubleshooting High-Availability Cluster Inspect and configure cluster logging Troubleshooting resource failures Troubleshooting cluster network issues Complex Resource Group Configuring an Active/Passive NFS Resource Group Lab Session Managing Constraints Types of constraints: Order, Location & Colocation Constraint Practice Lab Session Two Node Cluster Issues No room for node failure Split Brain Fence death/fence racing The cluster does not start until both nodes have started. Practice Lab Session Managing iSCSI Initiators iSCSI fundamentals Configuring an iSCSI Server Several types of backing Storage block, fileio, pscsi & ramdisk Creating iSCSI Target Lab Session to create a block backstore from the targetcli shell Managing High Availability Logical Volumes Clustered LVM & HA-LVM Lab Session to shared a disk (lun) to all cluster nodes Practice Lab Session on HA-LVM Managing Clustered Logical Volumes Active/Active configuration of logical volumes Distributed Lock Manager (DLM) for lock management clvmd daemon Practice Lab Session Global File System 2 (GFS2) GFS2 concepts Creating a GFS2 formatted Cluster File Systems Managing a GFS2 File System Managing a GFS2 Resource in the cluster Growing & Repairing a GFS2 File System
