Hi David,
thank you for the answer.
It seems that in case of a dedicated cluster network it is needed to have the monitors also connected to that network, otherwise ceph-deploy fails:
# ceph-deploy new --public-network 10.1.1.0/24 --cluster-network=10.3.3.0/24 monitor{1,2,3}
...
[2017-07-17 10:59:29,301][ceph_deploy][ERROR ] RuntimeError: subnet (10.3.3.0/24) is not valid for any of the ips found [u'10.1.1.5', u'192.168.100.5']
Kind regards,
Laszlo

Only the osds use the dedicated cluster network. Ping the mons and mds services on the network will do nothing.

Dear all,
I'm reading the docs at http://docs.ceph.com/docs/master/rados/configuration/network-config-ref/ regarding the cluster network and I wonder which nodes are connected to the dedicated cluster network?
The digram on the mentioned page only shows the OSDs connected to the cluster network, while the text says: "To support two networks, each Ceph Node will need to have more than one NIC." - which would mean that OSD + MON + MSD all should be connected to the dedicated cluster network. Which one is correct? Can I have the dedicated cluster network only for the OSDs? while the MONs are only connected to the public net?
Thank you!
Laszlo
