Hi,

Why not just add cluster network and public network to the global section ( http://ceph.com/docs/master/rados/configuration/network-config-ref/#ceph-networks ) ? The OSDs will pick their address when restarted. I did it once ( just once ;-) and it worked.

Hello to all,

I installed a ceph cluster using ceph-deploy and i am quite happy.

Now i want to add a cluster network to it. According to "ceph report" public_addr and cluster_addr are set to the same ip. How can i change this now?

Is it save to add something like this to my ceph.conf:

#( for 1 to 11 )
[osd.1]
   host = ceph-s01
   cluster addr = 10.0.0.1
   public addr = 192.168.55.1

#( for 11 to 23 )
[osd.11]
   host = ceph-s02
   cluster addr = 10.0.0.2
   public addr = 192.168.55.2

I'm a bit scared about crashing my existing osds and loosing all my data.

Thanks for your help
Stefan
