I suggest you should use opensuse leap 42.1 if you want to run business 
on the cluster, or opensuse tumbleweed if you
are just playing with HA stuff. It's because opensuse 13.2 is generally 
for desktop, leap 42.1 is similiar with centos, and tumbleweed
is roll distribution.  As for HA stuff, developers always make leap 
travel with SLE. For detailed description:

If you look back forward the mail list, you will see Kristoffer just release hawk2.0 lately.

What did the `crm status` dispaly? I think you should first make sure 
the whole cluster is OK.
It doesn't matter to hack that what your RAs configuration are.

If you're on leap and tumbleweed, install this package should be enough 
for a basic cluster:
#zypper in pacemaker corosync crmsh sbd  ha-cluster-bootstrap

Then, I recommend ha-cluster-bootstrap for you to set up cluster, really 
love it.
Look at here:

People can not help without relative message log in /var/log/message ;-)
