You can keep the public network in ceph.conf and can even remove that

Hi,
Please allow me to ask one more question:
We currently have a seperated network: cluster on 10.10.x.x and public
on 192.168.x.x.
I would like to migrate all network to 192.168.x.x setup, which would
give us 2*10G.
Is simply changing the cluster network in ceph.conf and a restart enough
We also build almost all of our clusters with a single Ceph network.
2x10 Gbit/s is almost never the bottleneck.

No, there is no big benefit unless your usecase (which 99% isn't) asks
for it.
Keep it simple, on
Realy?
I always thought that splitting the replication network is best practice.
Keeping everything in the same IPv6 network is much easier.
Thank you.

Hi,
I may be wrong, but AFAIK the cluster network is only used to bind the
corresponding functionality to the correct network interface. There's no
check for a common CIDR range or something similar in CEPH.
As long as the traffic is routeable from the current public network and
the new cl
2 Things about this. First, Mons do not communicate over the cluster
network. Only OSD daemons send any traffic over that network. Mons, MDS,
RGW, MGR, etc all communicate over the public network. OSDs communicate
with all clients, Mons, etc on the public network and with each other on
the clus
Hi!
When we installed our new luminous cluster, we had issues with the cluster
network (setup of mon's failed).
We moved on with a single network setup.
Now I would like to set the cluster network again but the cluster is in use
(4 nodes, 2 pools, VMs).
What happens if I set the cluster network o
