Ohh, sorry for the question, now I understand why we need to define
differents public networks in Ceph, I understand that clients contact
with the mon in order to obtain only the cluster map, from the
documentation:
"When a Ceph Client binds to a Ceph Monitor, it retrieves the latest
copy of the Cluster Map. With the cluster map, the client knows about
all of the monitors, OSDs, and metadata servers in the cluster"
I thought that mon's were some kind of gateway for all "ceph service"
and for them pass all Ceph traffic.
I need to read more ... sorry again.

Hi all, sorry, we are newbies in Ceph and we have a newbie question
about it. We have a Ceph cluster with three mon's and two public networks:
public network = 10.100.100.0/23,10.100.101.0/21
We have seen that ceph-mon are listen in only one of this network:
tcp 0 0 10.100.100.9:6789 0.0.0.0:* LISTEN 135385/ceph-mon
but not in the other public network necessary to access to cephfs from
this second network. We have seen that in principle that it's not
possible?:

http://lists.ceph.com/pipermail/ceph-users-ceph.com/2017-July/019659.html
and it's seems necessary to route the traffic from the second public
network to the first public network, but seeing this our question is why
you can define differents public networks in ceph if only you can access
to only one from the ceph-mon daemons? perhaps you can configure the
other mon's with the other public network? Or is there anything we're
not getting right?
Thank's in advance.
