Thank you for all your reply.
I will consider changing the design or negotiate with my colleagues for the
topology issue. Or if all are not working, try to come back to this
solution.
Cheers

No, mons can only have exactly one IP address and they'll only listen
on that IP.
As David suggested: check if you really need separate networks. This
setup usually creates more problems than it solves, especially if you
have one 1G and one 10G network.

I doubt you have a use case that requires you to have a different public
and private network. Just use 1 network on the 10Gb nics. There have been
plenty of mailing list threads in the last year along with testing and
production experience that indicate that having the networks separated is
not
Hello Paul,
Thanks for your reply.
Now my clients will be from 140.109 (LAN, the real ip network 1Gb/s) and
from 10.32 (SAN, a closed 10Gb network). Could I make this public_network
to be 0.0.0.0? so mon daemon listens on both 1Gb and 10Gb network?
Or could I have
public_network =
The cluster/private network is only used by the OSDs. Nothing else in ceph
or its clients communicate using it. Everything other than osd to osd
communication uses the public network. That includes the MONs, MDSs,
clients, and anything other than an osd talking to an osd. Nothing else
other than
All Ceph clients will always first connect to the mons. Mons provide
further information on the cluster such as the IPs of MDS and OSDs.
This means you need to provide the mon IPs to the mount command, not
the MDS IPs. Your first command works by coincidence since
you seem to run the mons and
Hello all,
I am testing the cephFS cluster so that clients could mount -t ceph.
the cluster has 6 nodes, 3 mons (also mds), and 3 osds.
All these 6 nodes has 2 nic, one 1Gb nic with real ip (140.109.0.0) and 1
10Gb nic with virtual ip (10.32.0.0)
140.109. Nic1 1G<-MDS1->Nic2 10G 10.32.
