I am able to Add a Ceph Monitor (step 3) as per the link http://ceph.com/docs/master/start/quick-ceph-deploy/ (Setting Up Ceph Storage Cluster)
But when I am executing the gatherkey command, I am getting the warnings(highlighted in yellow). Please find the details –
Command – “ceph-deploy gatherkeys vikrant” (vikrant is the hostname of the ceph-node1)
Output –
[ceph_deploy.cli][INFO ] Invoked (1.3.1):

I checked ceph.keyring is not generated for bootstrap-osd and bootstrap-mds in ceph-node1, due to which the next command “ceph-deploy osd prepare ceph-node2” is giving error.
Please find the setup details –
One Admin Node – from where I am executing ceph-deploy commands
Ceph-node1 – this is the ceph monitor, (hostname is vikrant)
Ceph-node2 – Ceph OSD, this is on a separate machine ( as of now I am trying to configure one OSD, in the link they have mentioned the example for two OSD)
Content of ceph.conf (this is same for admin node and ceph-node1)

Please let me know if you need any further information.
The intention is to setup a Ceph Block Device as per the link http://ceph.com/docs/master/start/quick-rbd/ , and it is mentioned in the link that Ceph Storage Cluster needs to be setup first before working with Ceph Block Device.
Please let me know your inputs on the above.
