There used to be a 5 minute quick start guide on the Ceph documentation-site, explaining how to do it using the "mkcephfs"-tool, but that seems to have been removed in favor of the new ceph-deploy method. You basically have to write your own "ceph.conf", prepare all of the data-dirs and mount-points on the nodes manually, make sure that password-less SSH to all nodes is OK and then run it. It will read your conf-file and create the cluster as described within that file. If any part fails, for example if you forgot to create a required directory on one of the nodes, you have to clean up what it has already done manually and try again. I understand why they deprecated it in favor of ceph-deploy and you wouldn't want to create a new cluster completely by hand, unless for learning. :-) Descriptions on how to add or remove components to/from an existing cluster manually are still on the documentation-site. For example: http://ceph.com/docs/master/rados/operations/add-or-rm-mons/ http://ceph.com/docs/master/rados/operations/add-or-rm-osds/ With this info, you should be able to manually build a new cluster, if you'd want to. Start with a fresh monitor, then add the rest.
