Hi, Thanks for the guide! I thought I had the same exact version...mine is also named "Pacemaker 1.1 Clusters from Scratch Creating Active/Passive and Active/Active Clusters on Fedora Edition 5", but my version of the document is meant for Fedora 17, and uses pcs and systemctl calls which don't exist on CentOS 6.5. I was trying to get it to work on CentOS 7 but realized support for DRBD on CentOS 7 is really lacking.
I'll refer to the version you posted from hereon.
