A new version of the DRBD User’s Guide is up at http://www.drbd.org/users-guide. As this version has some major additions to the previous release, I’ve decided to create a release
candidate this time, before declaring this an “official reference” — everyone’s feedback is requested and highly encouraged.
What’s new is Chapter 8, “Integrating DRBD with Pacemaker clusters“. It deals with the new drbd OCF resource agent we are about to release with 8.3.2, and how to use it in Pacemaker clusters using the CRM shell. It also has setup examples for MySQL, as does the legacy chapter on Heartbeat. Please grab the 8.3.2rc2 tarball if you are willing to help out testing this release candidate.
