Did you restart the OSD containers? Does ceph config show your changes?
ceph config get mon cluster_network
ceph config get mon public_network

Hi Eugen,
I did the same step specified but OSD is not updated cluster address.

I also expected at least some sort of impact, I just tested it in a
virtual lab environment. But besides the temporary "down" OSDs during
container restart the cluster was always responsive (although there's
no client traffic). I didn't even set "nodown". But all OSDs now have
a new backend address and the cluster seems to be happy.
Regards,
Eugen
