Hi Oliver,
This is my problem:
I have deployed Ceph AIO with two interfaces 192.168.1.67 and 10.0.0.67 but at the momento of installation I used 192.168.1.67 and I have an Openstack installed with two interfaces 192.168.1.65 and 10.0.0.65.
Openstack have the storage in Ceph but is working on 192.168.1.0/24 net and I need to work in 10.0.0.0/24 net.
If will do a tcpdump on ceph node and launch everything from openstack:
# tcpdump -i eth2 tcp and src host 10.0.0.65
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth2, link-type EN10MB (Ethernet), capture size 262144 bytes
Nothing appears and if I do with the other interface you can see it's working:
# tcpdump -i eth1 tcp and src host 192.168.1.65
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth1, link-type EN10MB (Ethernet), capture size 262144 bytes

This is my ceph.conf:
[global]
...
mon_initial_members = ceph-node
mon_host = 192.168.1.67
public_network = 192.168.1.0/24, 10.0.0.0/24
...
How I can change this for work with 10.0.0.0/24 net?
Thanks,
Fran.

Hi Fran,
public_network = the network of the clients to access ceph ressources
cluster_network = the network ceph use to keep the osd's sycronizing
themself
----
So if you want that your ceph cluster is available to public internet
addresses, you will have to assign IPs from a real public network.
That means not 10.0.0.0 / 192.168.0.0 and so on. But thats a logical
network design question and has nothing to do with ceph.
Of course you could, via iptables/what ever create rules to
masquarade/forward public ceph traffic to an internal, private network.
