I'm having problems, after changing the ceph.conf file and restarting a osd the cluster is always going to HEALTH_ERROR with blocked requests. Only by returning to the previous configuration and restarting the same osd make the cluster going to OK. So, my question is: is it possible to change the cluster network on a production ceph without stopping the service and destroying data? If so, how? > Short answer: Yes, Yes, Yes How? That totally depends. Keep in mind that Ceph just expects all daemons can talk to each other over IP. As long as you make sure the routing works, the firewalls allow the connections this can be done. How exactly depends on how you have set up your network configuration.
