My servers have 2 network boards each. I would
like to use the current

and use the second one to all Cephs processes to talk one to the
other.
Ceph support `cluster network` and `public network` options. Only OSD
work with cluster network. Any other is a OSD clients - public network.
Great. How do I migrate from my current single network board to a dual one?
Can I migrate servers one by one to the dual network setup or do I
have to stop the whole ceph cluster and restart it all already on the
dual setup?
Set the cluster_network in the ceph.conf and restart the OSDs one by one.
However, why not bond and use the additional bandwidth for both client
and cluster?
I don't see a major benefit in having separate cluster+public network
with Ceph. Seems like an old habit from back in the days.
LACP and one IP per node works just fine with Ceph.
