Hi Ajitha,
For one, it looks like you don't have enough OSDs for the number
of replicas you have specified in the config file. What is the
value of your 'osd pool default size' in ceph.conf? If it's "3",
for example, then you need to have at least 3 hosts with 1 OSD
each (with the default CRUSH rules, IIRC). Alternatively, you
could reduce the replication level. You can see how to do that
here:
http://ceph.com/docs/master/rados/operations/pools/#set-the-number-of-object-replicas
The other warning indicates that your monitor VM has a nearly full
disk.
Hope that helps!
Cheers,
Lincoln
