In Rocky multiple backend support is added as experimental feature. In order to take advantage of this feature it is decided to deprecate work_dir and node_staging_uri configuration options and reserve two filesystem stores 'os_glance_tasks_store' and 'os_glance_staging_store', which can be used to get rid of initializing store via internal functions. These internal stores are considered "reserved stores" by Glance. For the time being, these are hard-coded as filesystem stores. The store prefix 'os_glance_' is reserved for internal Glance use and the glance-api service will refuse to start if a store with this prefix is included in the enabled_backends config option in glance-api.conf. NOTE: Because there are no sensible default values for the location of the datadir for each of these stores, the operator must define 'os_glance_tasks_store' and 'os_glance_staging_store' in glance-api.conf configuration file as shown below. [os_glance_tasks_store] filesystem_store_datadir = /var/lib/glance/tasks_work_dir/ [os_glance_staging_store] filesystem_store_datadir = /var/lib/glance/staging/ Each filesystem store must have a unique datadir.
