Highly Available Services with DRBD and Pacemaker Training Course

Course Code

linuxha

Duration

7 hours (usually 1 day including breaks)

Requirements

  • General understanding of Linux block devices, filesystems, and TCP/IP networking
  • For the "Root filesystem on DRBD" topic: perfect understanding how a Linux system boots (initramfs, init, services, runlevels, ...)

Overview

The primary objective of this practical course is to introduce the Linux high-availability stack (Pacemaker, DRBD) to system administrators. During the training, each participant will build a two-machine cluster that offers a simple highly-available service (such as PostgreSQL or NFS) on a virtual IP address. Also, uses of DRBD not related to high availability are considered.
