Hi Daniel, I will open with I have absolutely no experience with cephadm, only bare-metal ceph, however in my experience adding a cluster network to an already existing cluster is as simple as adding the following line to the ceph.conf file on each node within the cluster: cluster network = X.X.X.X/XX >From there, setting the maintenance flags and doing rolling restarts of the services on each of the nodes then gets them back up with a cluster network. I think you can get away with only restarting the OSDs, but it's possible the MONs might be required too. Now, for cephadm I don't believe it uses the ceph conf file as much as a bare-metal ceph would, so you might be able to get away with something like: ceph config set global cluster_network X.X.X.X/XX But perhaps someone with more experience with cephadm than myself can let us know the better process for that.
