This is the issue.
My guess is someone ran "ceph osd set-require-min-compat-client
luminous", making it so that only luminous aware clients are allowed to
connect to the cluster. Kernel 4.12 doesn't support luminous features,
so it isn't allowed to connect. Perhaps you wanted to experiment with
the balancer module?
Thanks,
Ilya
