In Rocky we have added support for multiple backend as a EXPERIMENTAL
feature. However configuration options related to multiple backend
are not generated in sample config file due to some issue. We have
added below 2 new config options for multiple backend.
1. enabled_backneds (added in glance)
2. default_backend (added in glance_store)
Made provision to add all the above options to sample config
file.
