This may bot be a trivial thing to configure, but does RHEL 4.6 CS allow for 1 or more servers to belong to 1 or more clusters? Such as starting multiple cman, but just pointing it to use the appropriate cluster.conf. Are there different port assignments required to avoid network I/O conflicts? Just asking out loud, thanks.
