[Pacemaker] CMAN and Pacemaker

[Fil]

Hi everyone,

Happy holidays!

I need some help with adding CMAN to my current cluster config.
Currently I have a two node Corosync/Pacemaker (Active/Passive) cluster.
It works as expected. Now I need to add a distributed filesystem to my
setup. I would like to test GFS2. As much as I understand I need to
setup CMAN to manage dlm/gfs_controld, am I correct? I have followed the
Clusters_from_Scratch document but I am having issues starting
pacemakerd once the cman is up and running. Is it possible to use
dlm/gfs_controld without cman, directly from pacemaker? How do I strat
pacemaker when CMAN is running, and do I even need to, and if not how do
I manage my resources? Currently I am using:

Fedora 16
corosync-1.4.2-1.fc16.x86_64
pacemaker-1.1.6-4.fc16.x86_64
cman-3.1.7-1.fc16.x86_64

Thanks
filip
