This is the (unmodified) exit status of the process, so the resource
agent must be returning "4" for some reason. Normally, that is used to
indicate "insufficient privileges".

I would suspect that your user account has some privileges that the lrmd
user (typically hacluster:haclient) doesn't have. Try "su - hacluster"
first and see if it's any different. Maybe directory or file
permissions, or SELinux?
