This is a point we should settle in the upcoming changes to the OCF

The OCF 1.0 standard
merely says it means "Program is not configured". That is open to

has a more narrow view: "The resource's configuration is invalid. E.g.
required parameters are missing."

The reason Pacemaker considers it a fatal error is that it expects it to
be returned only for an error in the resource agent's configuration *in
the cluster*. If the cluster config is bad, it doesn't matter which node
we try it on. For example, if an agent takes a parameter "frobble" with
valid values from 1 to 10, and the user supplies "frobble=-1", that
would be a configuration error.

I think in OCF 2.0 we should distinguish "supplied RA parameters are
bad" from "service's configuration on this host is bad". Currently,
Pacemaker expects the latter error to generate OCF_ERR_GENERIC,
OCF_ERR_ARGS, OCF_ERR_PERM, or OCF_ERR_INSTALLED, which allows it to try
the resource on another node.
