Andrew, before I get too far with compiling the latest corosync and pacemaker, do you have your packages publicly available in a PPA or similar?

I think you'll have the best results if you work with the latest version of these services so that you don't run into bugs that have since been fixed. If you simply build them from source and do "make install", it should be pretty straightforward. If, like me, you want to create packages to deploy on your production servers, then there's a bit more work to be done. On Ubuntu, Pacemaker and Corosync depend on the cluster-glue and resource-agents packages. I've been told that there should be no problem using the versions of these packages provided in 12.04 with the latest versions of Corosync and Pacemaker. The new version of Corosync also introduces a new dependency, libqb (http://www.libqb.org/). You can also build this from source. >From repositories: cluster-glue resource-agents >From source: libqb corosync pacemaker Part of the complexity of building packages for Corosync and Pacemaker is that Ubuntu divides these source packages up into a number of binary packages, as defined here: http://packages.ubuntu.com/source/precise/corosync http://packages.ubuntu.com/source/precise/pacemaker Thus when you compile your own version of Corosync or Pacemaker, you don't want to have any of those packages installed. I'd recommend using apt's "build-dep" option for installing all of the dependencies you'll need to build Corosync and Pacemaker from source: apt-get build-dep corosync apt-get build-dep pacemaker In regards to the cluster you set up, can you post your Pacemaker CIB or additional details about your configuration? I think Corosync + Pacemaker + DRBD should work well for what you'd like to do.
