If a service becomes slow, unresponsive, or shows a status of Failed, you can repair it. If you change the configuration of a service you use the same process to restart it.
Repairing a service stops and restarts the service on each instance on which it's running.
If you change the cluster name (cluster hostname), you must repair the S3 Gateway services for the change to take effect.
If you regenerate or upload an SSL certificate, you must repair the S3 Gateway and MAPI services for the change to take effect.
If you upload an SSL certificate for access to a remote system for bucket synchronization, you must repair the Policy Engine and MAPI services for the change to take effect.
Important: Depending on which service you're repairing, parts of the system will be unavailable until the repair finishes.
