None, because dual-Primary and OCFS2 are utterly pointless for Apache
and MySQL. Apache and MySQL can be easily built on single-Primary DRBD
with a regular filesystem (ext3/4, XFS, you name it).

Well, a Corosync service won't work too well if your cluster is built
on Heartbeat, which it looks like it is. :) So if you really must use
OCFS2 (which I think you don't), switch that Heartbeat/Pacemaker
cluster to Corosync/Pacemaker.

Cheers,
Florian
