Hi Yenya,
Can I ask how your cluster looks and why you want to do the network splitting?
We used to set up 9-12 OSD nodes (12-16 HDDs each) clusters using 2x10Gb for access and 2x10Gb for cluster network, however, I don't see the reasons to not use just one network for next cluster setup.
Thanks
Jakub

Hello, Ceph users,
is it possible to migrate already deployed Ceph cluster, which uses
public network only, to a split public/dedicated networks? If so,
can this be done without service disruption? I have now got a new
hardware which makes this possible, but I am not sure how to do it.
Another question is whether the cluster network can be done
solely on top of IPv6 link-local addresses without any public address prefix.
When deploying this cluster (Ceph Firefly, IIRC), I had problems
with mixed IPv4/IPv6 addressing, and ended up with ms_bind_ipv6 = false
in my Ceph conf.
Thanks,
-Yenya
