cephadm

Deploy and manage a Ceph cluster using containers. Part of the Ceph orchestrator framework. More information: https://docs.ceph.com/en/latest/man/8/cephadm/.

• Bootstrap a new Ceph cluster on the current host:

sudo cephadm bootstrap --mon-ip {{monitor_ip}}

• Add a new host to the cluster:

sudo cephadm add-host {{hostname}} {{ip_address}}

• Deploy a specific service (e.g., mgr, mon, osd):

sudo cephadm deploy {{service_type}} --name {{service_name}}

• Check the status of cluster services:

sudo cephadm shell -- ceph {{[-s|--status]}}

• Enter a shell environment inside the Ceph container:

sudo cephadm shell

• Remove a service from the cluster:

sudo cephadm rm-service {{service_type}} --name {{service_name}}
