There’s also a Maintenance mode that you can set for each server, as you’re doing updates, so that the cluster doesn’t try to move data from affected OSD’s, while the server being updated is offline or down. I’ve worked some on automating this with Ansible, but have found my process (and/or my cluster) still requires some manual intervention while it’s running to get things done cleanly.
