[ClusterLabs] I question whether STONITH is working.

I have 2 Fedora VMs (node1, and node2) running on a Windows 10 machine 
using Virtualbox.

I began with this.
http://clusterlabs.org/doc/en-US/Pacemaker/1.1-pcs/html-single/Clusters_from_Scratch/

When it came to fencing, I refered to this.
http://www.linux-ha.org/wiki/SBD_Fencing

To the file /etc/sysconfig/sbd I added these lines.
SBD_OPTS="-W"
SBD_DEVICE="/dev/sdb1"
I added 'modprobe softdog' to rc.local

After getting sbd working, I resumed with Clusters from Scratch, chapter 
8.3.
I executed these commands *only* one node1.  Am I suppose to run any of 
these commands on other nodes? 'Clusters from Scratch' does not specify.
pcs cluster cib stonith_cfg
pcs -f stonith_cfg stonith create sbd-fence fence_sbd devices="/dev/sdb1" 
port="node2"
pcs -f stonith_cfg property set stonith-enabled=true
pcs cluster cib-push stonith_cfg

I then tried this command from node1.
stonith_admin --reboot node2

Node2 did not reboot or even shutdown. the command 'sbd -d /dev/sdb1 list' 
showed node2 as off, but I was still logged into it (cluster status on 
node2 showed not running).

I rebooted and ran this command on node 2 and started cluster.
sbd -d /dev/sdb1 message node2 clear

If I ran this command on node2, node2 rebooted.
stonith_admin --reboot node1

What have I missed or done wrong?


Thank you,
