Could someone make a quick clarification on the quick start guide for me? On
this page: http://ceph.com/docs/next/start/quick-ceph-deploy/. After I do
"ceph-deploy new" to a system is that system then a monitor from that point
forward? Or do I then have to do "ceph-deploy mon create" to that same system
before it is really a monitor?
Regardless of the combinations of systems I try I seem to get a failure at the
add a monitor step. Should this be a correct sequence?
ceph@cephtest01:~$ ceph-deploy new cephtest02
ceph@cephtest01:~$ ceph-deploy install --no-adjust-repos cephtest02
cephtest03 cephtest04
ceph@cephtest01:~$ ceph-deploy mon create cephtest02
Here is the failure I get:

Not clear if I should be using the same system from "ceph-deploy new" for
"ceph-deploy mon" but the same thing happens either way:
ceph@cephtest01:~$ ssh cephtest03 "sudo ceph-mon --cluster ceph --mkfs -i
cephtest02 --keyring /var/lib/ceph/tmp/ceph-cephtest02.mon.keyring"
