Hi,
you can specify a customized ceph.conf before the 'cephadm bootstrap'
command [1] to add a dedicated cluster network (if you really need
that, it has been discussed extensively on the list):
---snip---
octo1:~ # cat <<EOF > /root/ceph.conf
[global]
public network = 192.168.124.0/24
cluster network = 192.168.127.0/24
EOF
octo1:~ # cephadm bootstrap -c /root/ceph.conf --mon-ip 192.168.124.5
[...]
---snip---
After you deployed the OSDs they should be attached to the cluster network:
---snip---
octo1:~ # ceph osd metadata 0 | grep addr
"back_addr":
"[v2:192.168.127.11:6800/4272275002,v1:192.168.127.11:6801/4272275002]",
"front_addr":
"[v2:192.168.124.5:6802/4272275002,v1:192.168.124.5:6803/4272275002]",
"hb_back_addr":
"[v2:192.168.127.11:6802/4272275002,v1:192.168.127.11:6803/4272275002]",
"hb_front_addr":
"[v2:192.168.124.5:6804/4272275002,v1:192.168.124.5:6805/4272275002]",
---snip---
You should see the replication traffic on the respective interfaces.

Eugen

I am new to Ceph so I hope this is not a question
of me not reading the
documentation well enough.
I have setup a small cluster to learn with three physical hosts each with
two nics.
The cluster is upp and running but I have not figured out how to tie the
OSD:s to my second interface for a separate cluster network, as it is now
all communication goes thru the public network.
Is it possible to define the cluster network with cephadm in some way?
