Hm. let me try to summarize my understanding of this thread. Hostnames are in general case insensitive. In pacemaker/openais/heartbeat, in most places, this is correctly taken care of by using strcasecmp(3) or tolower(3) in C code where appropriate. some stonith plugins however seem to be case sensitive, and will just break when one uses hostnames with inappropriate case. Hideo-san proposes to fix that stonith plugin, to make it deal with hostnames case insensitive as well (as the rest of the cluster stack and dns and whatever does), but to warn about the fact that there is some case mismatch between spelling in some config file and "hostlist detection" of the stonith plugin. Hideo-san, if my understanding of your proposal is correct, then I think that should just be done. makes the code more robust, follows principle of least surprise etc. there may even be plugins that can only "autodetect" in all caps because of limitations in the firmware of the hardware used. I don't know. but either folding hostnames to all lowercase, or using strcasecmp, sounds reasonable.
