[Pacemaker] pcmk + corosync + cman for dlm support?

[Nick Khamis]

Hello Everyone,

I just want to make sure this is still the case before I go through
with it. I am trying to setup an
active/active using:

Corosync 1.4.2
Pacemaker 1.1.6
Cluster3
DRBD 8.3.7
OCFS2

The only reason I installed Cluster3 was for dlm support. Fencing
would be handled by stonithd.
Is there any reason I need to fully install and configure two cluster
managers. Defining nodes in
both cman and corosync/openais?

Thanks in Advance,

Nick.
