Hi,
I want to implement two scenarios:
-------------------
1. Store the sample cirrOS image in ceph block device and use it to boot the VMs.
2. Use the ceph block device as a volume and attach it to the VMs.
Thanks
Kumar

Hi,
Now I am integrating ceph with openstack. I have installed openstack . Now to test ceph,
how do I create a ceph block device and store the sample cirrOS image in it and use it for booting VMs ?
Thanks
Kumar

ceph-deploy is not able to add new monitors, this is a feature that is actually being worked on at the moment
See
http://tracker.ceph.com/issues/6638You will need to do this manually and specify all the things you are missing following the Ceph docs here

Hi,
I am new user of ceph. I have installed a three node cluster following
the ceph document. I have added OSDs and initial monitor.
But while adding additional monitors, I am receiving this error as
shown below.
