Deploy and configure these services I'm pretty new to Ceph, so I've included all my steps I used to set up my cluster since I'm not sure what is or is not useful information to fix my problem. Failing to include a service_id in your OSD spec causes the Ceph cluster to mix the OSDs from your spec with those OSDs, which can potentially result in the overwriting of service specs created by cephadm to track them. run. However, a ceph cluster also uses other types of daemons for monitoring, management and non-native protocol support The ceph orch daemon command provides subcommands for tasks such as starting, stopping, restarting, reconfig daemons, e. For example, SATA drives implement a standard called SMART that provides a wide range of On the other hand, it could be very convenient if `ceph orch upgrade status` reported that the upgrade is actually 'paused' because, from an automation point of view, there's nothing to detect that the upgrade is paused.
