Description
if there is only mon_host= ip1, ip2...in the ceph.conf, then "ceph ping mon.<id>" doesn't work.
Root cause is in the librados::RadosClient::ping_monitor() implementation:
it calls build_initial_monmap() to generate monmap. that's only a initial monmap version generated from local ceph.conf file.
if there is no mon_id in ceph.conf, then this initial monmap will name the monitors with mon.noname-a, mon.noname-b, etc.

so "ceph ping mon.<id>" will remind you mon.<id> doesn't existed. however, if you run "ceph ping mon.a", you can get the reply. The problem is there is no "mon.a" in my cluster system.
