Fencing from within dlm_controld.pcmk still did not work with your first
patch against that _no_mainloop function (expected).

So I did my best to build packages from the current git tree.

Voila! I got failed node correctly fenced!
I'll do some more extensive testing next days, but I believe everything
should be much better now.

I knew you're genius he-he ;)

So, here are steps to get DLM handle CPG NODEDOWN events correctly with
pacemaker using openais stack:

1. Build pacemaker (as of 2011-09-28) from git.
2. Apply attached patches to cluster-3.0.17 source tree.
3. Build dlm_controld.pcmk

One note - gfs2_controld probably needs to be fixed too (FIXME).

Best regards,
Vladislav
