ceph orch daemon reconfig <name>
Rotating a daemon's authenticate key
------------------------------------
All Ceph and gateway daemons in the cluster have a secret key that is used to connect
to and authenticate with the cluster. This key can be rotated (i.e., replaced with a
new key) with the following command:
.. prompt:: bash #
ceph orch daemon rotate-key <name>
For MDS, OSD, and MGR daemons, this does not require a daemon restart. For other
daemons, however (e.g., RGW), the daemon may be restarted to switch to the new key.
