New Article: Detect Failures and Ensure High Availability: DRBD and Corosync/Pacemaker

by Posted on
My latest article is now available on the ADMIN Magazine website (and issue 73 of ADMIN Magazine) and is called “Detect Failures and Ensure High Availability: DRBD and Corosync/Pacemaker.” ADMIN Magazine is owned by Linux News Media, owners of Linux Magazine.

Many clustering and high-availability frameworks have been developed for Linux, but in this article, I focus on the more mainstream and widely used Corosync and Pacemaker service and DRBD. If you follow along, you’ll learn how to configure an active-passive dual-node cluster that replicates local storage (accessed and written to/read from vital applications or services) to its neighboring node. In this way, you’ll be able to host and serve data requests, so long as a single node of the cluster remains online.
