>From the best practices section of the wiki: One process for one export works best with the current codebase. (Sharing a namespace export in the same server is not a problem And from the faq from mailing list, first question Q > So the question is, what makes this different from running two instances on different ports? What kind of check is being done in glusterfsd and what are the reasons that this should be prevented? A You can run multiple glusterfsd instances on the same machine. the PID file is only a mechanism which helps you write init.d scripts neatly. things you need to take care - 1. if you are specifying pidfile, do not specify the same path for multiple daemons 2. do not export the same backend directory with different glusterfsd daemons. 3. take care to see to that both do not try to bind to the same tcp port etc. apart from that, the two daemons are oblivious to each other and they can have same volume names defined as well. Make sure client and server runs same version of GlusterFS. ------------------- So what does this mean and is it current? If someone needs to export more than one directory, should they run multiple glusterfsd processes and configs, or should they configure multiple export bricks and use only a single glusterfsd process?
