Pacemaker is also unique among cluster managers that it We already talked on IRC, but just to clarify this to all: How many OSDs to run (on what hosts) is a question about the available & correctly-functioning storage devices, not really about the administrators wishes. If you want to run more, plug in more hard drives; starting OSDs without them having a backing store is not helpful. The planned architecture handles this automatically, triggering based on the udev "new block device detected" hook. And that's one of the reasons /etc/init.d/ceph-osd just isn't good enough for the brave new world. -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
