You've configured the cluster so that no node is eligible to run
resources unless you allow it (when you turned off symmetric
clustering). So you need to provide explicit location constraints to
allow the ping resource to run. (And you probably want to clone it.)

Or, easiest, don't switch to asymmetric clustering. I don't think that's
what you want.
