Most installations I do are done by bootstrapping the monitors and osds manually. I have some homebrew scripts for this, but I mainly use Puppet to make sure all the packages and configuration is present on the nodes and afterwards it's just a matter of adding the OSDs and formatting their disks once. The guide to bootstrapping a monitor: http://eu.ceph.com/docs/master/dev/mon-bootstrap/ When the monitor cluster is running you can start generating cephx keys for the OSDs and add them to the cluster: http://eu.ceph.com/docs/master/rados/operations/add-or-rm-osds/ I don't know if the docs are 100% correct. I've done this so many times that I do a lot of things without even reading the docs, so there might be a typo in it somewhere. If so, report it so it can be fixed. Where I think that ceph-deploy works for a lot of people I fully understand that some people just want to manually bootstrap a Ceph cluster from scratch.
