That's lucky, but not guaranteed if the timing is wrong. Certainly you
can do that and not hit the monitor.

If you read the CIB, you will find that you have target_role both as an
instance_ and as a meta_attribute, which is exactly your problem. They
are set to conflicting values and so the cluster's behaviour is
undefined. As I've written - please read ;-) -, newer versions would
warn about this.
In your version, you're better off deleting the instance_attribute (via
crm_resource) and from then on invoking crm_resource with --meta to
modify the meta_attribute instead.
