I think heartbeats will failover to the public network if the private doesn't work -- may not have always done that.
Hi Cephadm Reef 18.2.0. We would like to remove our cluster_network without stopping the cluster and without having to route between the networks. global advanced cluster_network 192.168.100.0/24 * global advanced public_network 172.21.12.0/22 * The documentation[1] states: " You may specifically assign static IP addresses or override cluster_network settings using the cluster_addr setting for specific OSD daemons. " So for one OSD at a time I could set cluster_addr to override the cluster_network IP and use the public_network IP instead? As the containers are using host networking they have access to both IPs and will just layer 2 the traffic, avoiding routing? When all OSDs are running with a public_network IP set via cluster_addr we can just delete the cluster_network setting and then remove all the ceph_addr settings, as with no cluster_network setting the public_network setting will be used? We tried with one OSD and it seems to work. Anyone see a problem with this approach?
Turned out to be even simpler for this setup where the OSD containers have access til both host networks:
1) ceph config rm global cluster_network -> nothing happened, no automatic redeploy or restart
2) Restart OSDs
Mvh.
