Methodology

Online

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.

About this course
