In retrospect I should have used the long (fqdn) of the nodes rather
than the short names, which as reportd, are not node names.

I tried to use the node names (fqdn) when adding the fence_topology
resource to the cib but I always got an error from crm telling me of an
invalid DTD/schema. In the end I had to add a 'dummy' attributes to each
nodes (dummy=<node_name>) and use them to create the fence levels, as
in:

    crm configure fencing_topology \
    attr:dummy=node1 fence_node1_ipmi fence_node1_psu1_off,fence_node1_psu2_off,fence_node1_psu1_on,fence_node1_psu2_on \
    attr:dummy=node2 fence_node2_ipmi fence_node2_psu1_off,fence_node2_psu2_off,fence_node2_psu1_on,fence_node2_psu2_on

Is this the expected behaviour?

Thanks,
