How can I set resource stickiness in pacemaker?

I'm playing around with Red Hat's High Availability Add-On, everything seems working fine however I have one issue:

Whenever I reboot one of nodes 7test2, resource group g1 migrates to 7test1 (by design) and then when 7test2 comes back online resource group g1 migrates back, it's like it has some sort of stickiness or something.

[root@7test1 ~]# cat /etc/redhat-release 
Red Hat Enterprise Linux Server release 7.1 (Maipo)
[root@7test1 ~]# rpm -q pcs

You can set the value of resource-stickiness, a resource meta option that indicates how much the resource prefers to stay where it is (the default value is 0) for a given resource or group whith the following command:

# pcs resource meta resource_id resource-stickiness=100

For example:

# pcs resource meta dns_ip resource-stickiness=100

# pcs resource show dns_ip Resource: dns_ip (class=ocf provider=heartbeat type=IPaddr2) Attributes: ip=10.0.0.1 cidr_netmask=24 Meta Attrs: resource-stickiness=100 Operations: start interval=0s timeout=20s (dns_ip-start-timeout-20s)

To display the current value of a specific cluster property, use the following command.

pcs property list --all
