Cinder.conf: Overview

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 systemctl openstack-cinder-api restart or systemctl 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.

Note

Block Storage V2 API has been deprecated. To ensure Cinder does not use the V2 API, update enable_v2_api=false and enable_v3_api=true in your cinder.conf file.
