[ceph-users] How to tune the ceph balancer in nautilus

Hi, I playing around with the ceph balancer in luminous and nautilus. While tuning some balancer settings I experienced some problems with nautilus. In Luminous I cold configure the max_misplaced value like this: ceph config-key set mgr/balancer/max_misplaced 0.002 With the same command in nautilus I get this Warning: WARNING: it looks like you might be trying to set a ceph-mgr module configuration key. Since Ceph 13.0.0 (Mimic), mgr module configuration is done with `config set`, and new values set using `config-key set` will be ignored. After investigating the nautilus documentation (https://docs.ceph.com/docs/nautilus/rados/operations/balancer/#throttling) I tried this: ceph config set mgr mgr/balancer/max_misplaced 0.002 and get this error: Error EINVAL: unrecognized config option 'mgr/balancer/max_misplaced' My question is, how can I configure this parameters? In general the whole "ceph config" foo confuses me a bit. ceph version 14.2.2 (4f8fa0a0024755aae7d95567c63f11d6862d55be) nautilus (stable) Regards Manuel
