Keys Management

Gather Keys

Before you can provision a host to run OSDs or metadata servers, you must gather monitor keys and the OSD and MDS bootstrap keyrings. To gather keys, enter the following:

ceph-deploy gatherkeys {monitor-host}


To retrieve the keys, you specify a host that has a Ceph monitor.


If you have specified multiple monitors in the setup of the cluster, make sure, that all monitors are up and running. If the monitors haven’t formed quorum, ceph-create-keys will not finish and the keys aren’t generated.

Forget Keys

When you are no longer using ceph-deploy (or if you are recreating a cluster), you should delete the keys in the local directory of your admin host. To delete keys, enter the following:

ceph-deploy forgetkeys
