What is true way to separate ceph cluster/public network?

[Donitoza]

Hello!

I have a ceph cluster with same public and cluster network.
What is true way to separate ceph cluster/public network in the production?
Is it really without stopping all vm`s?

Thanks!

P.S. Virtual Environment 5.1-46

Some thoughts:
I can migrate VMs (kvm and lxc) between nodes and restart nodes without guests one by one.
As a result I separate nodes networks, but how split ceph cluster/public network settings without stopping all VMs

Any Idea?
