Cinder is configured by changing the contents of the cinder.conf file and restarting all of the Cinder processes. Depending on the OpenStack distribution used, this may require issuing commands such as service openstack-cinder-api restart or service cinder-api restart.


The cinder.conf file contains a set of configuration options (one per line), specified as option_name=value. Configuration options are grouped together into a stanza, denoted by [stanza_name]. There must be at least one stanza named [DEFAULT] that contains configuration parameters that apply generically to Cinder (and not to any particular backend). Configuration options that are associated with a particular Cinder backend should be placed in a separate stanza.


While it is possible to specify driver-specific configuration options within the [DEFAULT] stanza, you are unable to define multiple Cinder backends within the [DEFAULT] stanza. NetApp strongly recommends that you specify driver-specific configuration in separate named stanzas, being sure to list the backends that should be enabled as the value for the configuration option enabled_backends; for example:


The enabled_backends option should be specified within the [DEFAULT] configuration stanza.
