When Fuel deploys Ceph we set the GPT partition typecode (using sgdisk [0]) for OSD and journal partitions. Ceph installs udev rules [1] that will find all partitions containing these GUIDs and activate them as needed. If you're going to deploy new OSDs manually you'll probably want to set the partition GUIDs.
