I guess this would be the most complicated way. Better would be to take a
route "Everybody talks to CMAN"
(http://blog.clusterlabs.org/blog/2012/pacemaker-and-cluster-filesystems/):

1.       Filesystems supported: GFS2, OCFS2

2.       Corosync: 1.x

3.       Pacemaker: 1.1.6 or later

4.       Other: cman, openais

 

Best regards,
