[Pacemaker] vip can not back to active/active status after failover

[WenWen]

Hi, 
I am doing active/active cluster with drbd pacemaker and apache.
when i start cman and pacemaker service on both nodes at the first time
everything is ok.

then I set node1 to standby then online again.
The apache and VIP can not back to active/active again.

vip and apache service only run on one node.
Becoz we set the colocation to the vip and apache resource.

is it the design?

hope somebody can help me.
Here is my configuration file.
