After the course you can build Linux services and storage so that losing one server does not stop operations. You set up load balancing with LVS, keepalived and HAProxy, run failover clusters with Pacemaker and Corosync, provide storage with DRBD, GFS2, GlusterFS and Ceph and make single servers more robust with RAID, LVM and bonding. The course is aimed at experienced Linux administrators and infrastructure engineers with LPIC-2 knowledge who are preparing for exam 306-300.
What you’ll take away.
- Apply cluster concepts such as quorum, fencing and split brain with confidence
- Set up load-balanced clusters with LVS, keepalived and HAProxy
- Run failover clusters with Pacemaker and Corosync
- Provide shared and distributed storage with DRBD, iSCSI, GFS2, OCFS2, GlusterFS and Ceph
- Make single servers more robust with RAID, LVM, network bonding and hardware monitoring
Your training in detail
- Who is it for?
- Linux administrators and infrastructure and storage engineers who plan and run highly available services and storage clusters and are working towards LPIC-3.
- Prerequisites
- Confident Linux administration at LPIC-2 level and a basic grasp of networking and storage. For the certification, LPI requires an active LPIC-2 certification.
- Format & planning
- Standard length: 5 training days. A different length can be arranged for companies.
Agenda: from understanding to application
Our independently developed agenda proposal. Focus areas, lab environment and scope are agreed before booking.
High availability: cluster types, quorum, fencing, MTBF and MTTR
Load-balanced clusters with LVS, keepalived, ldirectord and HAProxy
Failover clusters with Pacemaker, Corosync and STONITH
Cluster storage: DRBD, iSCSI, multipath, GFS2 and OCFS2
Distributed storage with GlusterFS and Ceph
Single node: SMART, UPS, RAID, LVM and network bonding
Exam practice for the 306-300 objectives
In a lab you build a two-node failover cluster with Pacemaker and Corosync, put the data on DRBD, configure fencing and simulate a node failure. You then extend the setup with a small Ceph cluster.
