I've got ceph up and running on a 3-node centos 6.4 cluster. However, after I
a) set the cluster to nout as follows: ceph osd set noout b) rebooted 1 node c) logged into that 1 node, I tried to do: service ceph start osd.12 but it returned with error message: /etc/init.d/ceph: osd.12 not found (/etc/ceph/ceph.conf defines , /var/lib/ceph defines ) Now, it *IS* true that the /etc/ceph/ceph.conf does NOT make any reference to osd.12. Am I supposed to *manually* update the master ceph.conf file to put each and ever osd reference into (osd.1 through osd 14 in my case) and then copy the ceph.conf file to each node? I would have thought that when I add a new osd (using ceph-deploy) that it would *automatically* update either a) the master ceph.conf file on my admin machine (where ceph-deploy runs) or least it would update the ceph.conf file on the node that contains the osd that's being added. It feels as if ceph-deploy will allow you to add osds, but this addition only updates the "in-memory" definitions of ceph.conf, and that after server reboot, it looses the in-memory definitions and attempts to re-read info from ceph.conf. Is this correct? If so, is there a way when using ceph-deploy to get it to automtically create the necessary entries for the ceph.conf file? If so, how? If not, then am we supposed to both a) use ceph-deploy to add osds and then b) manually edit ceph.conf? If so, isn't that dangerous/error prone? Or am I missing something fundamental? (I'm using ceph version 0.72.1).
