After following the wiki example for sharing an IP address (http://clusterlabs.org/wiki/Example_configurations), I'm
able to manually fail over the resource with crm using the following statement (my nodes are ha1 and ha2):
crm resource migrate failover-ip ha2
However, if I halt the box which currently owns the floating IP, or otherwise abruptly kill networking on it, the
failover never automatically happens. I did follow the example explicitly, and the resource was initially created with:
primitive failover-ip ocf:heartbeat:IPaddr params ip=192.168.7.250 op
monitor interval=10
...so I'm not quite sure what the issue is. The messaging layer seems to work since crm status shows the node as being
down, but the resource allocation layer seems to be failing, probably somewhere in the CRM...?
I have no firewall between these nodes, so I haven't run tcpdump either to see if the messages are making it, but I
can't imagine that that's the issue here. This is what things look like after the simulated problem:

As you can see, nothing has happened. Hopefully someone else can identify my mistake before I do after having read
this. Thanks in advance for any help.
