From installing Pacemaker/Corosync HA clusters and configuring STONITH fencing to clustered fail-over services with shared iSCSI/LVM storage, GFS2 shared filesystems, cluster monitoring, and service behaviour constraints — master every HA skill in EX436.
From installing Pacemaker/Corosync clusters and STONITH fencing to clustered fail-over services, GFS2 shared filesystems, iSCSI multipath storage, HA LVM, monitoring, and service location constraints.
Master Pacemaker and Corosync HA cluster installation with Ansible, quorum configuration, STONITH fencing with fence_ipmilan, cluster logging to journald, monitoring resources with alerts, clustered fail-over services with shared iSCSI storage and virtual IPs, location and order constraints, iSCSI multipath access, shared LVM and HA LVM devices, and GFS2 shared filesystems across multiple nodes.
Install Pacemaker/Corosync manually or via Ansible, configure cluster quorum options for split-brain protection.
Configure fence_ipmilan and other fence agents, test fencing, ensure all nodes can fence all others.
Configure iSCSI initiators, create shared storage, configure multipath, shared LVM, and HA LVM devices.
Configure clustered fail-over services with resource groups, shared storage, and virtual IPs. Restrict service placement with location constraints and configure failover ordering. Create and manage GFS2 shared filesystems across all cluster nodes simultaneously with per-node journals.
Configure cluster logging per node, forward to journald, create monitoring resources, configure alerts and email notifications.
Create GFS2 on LVs, configure shared multi-node mounting, manage GFS2, add journals for additional nodes.
Pacemaker and Corosync power high-availability services at banks, telcos, and enterprise data centres where downtime is not an option. EX436 certifies you can build and manage those clusters.
Banks, telcos, and hospitals run their most critical Linux services on Pacemaker HA clusters. EX436 certifies you can build and manage those clusters reliably.
EX436 is a hands-on exam on real RHEL systems — you install Pacemaker, configure fencing, create resources, and manage GFS2 storage under actual exam conditions.
HA clustering is a rare, specialized skill. Certified Pacemaker/Corosync administrators command premium salaries at data centres, banks, and telcos.
Our curriculum covers every EX436 objective — cluster installation, STONITH, logging, monitoring, fail-over services, service constraints, iSCSI/LVM storage, and GFS2.
Practise on real multi-node RHEL 9 clusters with Pacemaker 2.x — every module includes pcs CLI hands-on tasks aligned to exam objectives.
