[Pacemaker] No resource failback with no stickiness - why ?

Hi,

I'm using Pacemaker 1.1.6 and corosync 1.4.2 under Fedora Core 16, using 
default rpms from repositories.

I'm trying to get a working Pacemaker cluster and I'm testing it by 
creating the "cluster from cratch configuration" from
http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf. 
<http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf>

I already worked with pacemaker 1.0.x two years ago, and it worked well 
(with the older documentation).

I'm encountering a problem. I added my IPAddr resource and tried 
failvover/failback. So I stop my first node, and my resource moves to 
node2. After a minute I restart node1, but my resource doesn't come 
back, my resource stays on node2.

As explained page 49, my resource should go back to node1. I didn't 
apply any stickiness value to my resource or in rsc_default. Did the 
behavior changed in this release ?

How to make it working ?

Thanks for your help.
