Hello Andrew, Thank you so much for your response. I did manage to get an active/active cluster working using cman+pacemaker. Everything works fine except for the occasional error from fenced, and a kernel crash from ocfs2_controld.cman.

I believe I have most of the pieces needed to build a pcmk only active/active, (i.e., pcmk + corosync/openais, standard dlm_controld, and ocfs2_controld.pcmk). When attempting to start the cluster: aisexec /etc/init.d/pacemaker start root 1189 0.3 1.3 62980 3400 ?

Local node id: 6 1321832187 setup_stack@174: Added Pacemaker as client 1 with fd -1 It is with the help of the LHA community that enabled me to progress as much as I have, and I do really apreicate it. I wish I could disclose more information on why we don't just use binaries included in a distro for a pcmk only active/active however, all I am entitled to say is that it is a requirement to achieve this using source built from scratch.
