Managing hosts

As a storage administrator, you can use the Ceph Orchestrator with cephadm in the backend to add, list, and remove hosts in an existing IBM Storage Ceph cluster.

You can also add labels to hosts. Labels are free-form and have no specific meanings. Each host can have multiple labels. For example, apply the mon label to all hosts that have monitor daemons deployed, mgr for all hosts with manager daemons deployed, rgw for Ceph Object Gateways, and so on.

Labeling all the hosts in the storage cluster helps to simplify system management tasks by allowing you to quickly identify the daemons running on each host. In addition, you can use the Ceph Orchestrator or a YAML file to deploy or remove daemons on hosts that have specific host labels.
