	</pre>		</pre>

			Depending on the ID of the OSD created, you'll need to create an init entry for each OSD and start it like so.
			<pre>
			ln -s ceph /etc/init.d/ceph-osd.<OID_ID>
			rc-update add ceph-osd.<OID_ID>
			openrc
			</pre>
			(note: you can discover the OSD IDs present on the host with <code>ceph-volume osd list</code>)
