Hi,

We have some work to do on our power lines for all building and we have to shut down all systems. So there is also no traffic on any ceph client.

Pitty, we have to shot down some ceph nodes too in an affected building.

To avoid rebalancing - as I see there is no need for it, as there is no traffic on clients - how can I safely set the remaining cluster nodes in a „keep calm and wait“ state?

Is that the noout option?

Thanks for feedback and suggestions! Regards . Götz
