Overview
We should be able to support Cinder-multi-backend
This moving this way would allow us to support multiple concurent backends.
user story
Use a single cinder-volume backend
currently you can
class { 'cinder::volume': } class { 'cinder::volume::iscsi': iscsi_ip_address => '10.0.0.2', }
Use two or more cinder-volume backends and assign them to different types
class { 'cinder::volume': } cinder::backend::rbd {'images': rbd_user => 'images', rbd_pool => 'images', } cinder::backend::iscsi {'local-lvm': iscsi_ip_address => '10.0.0.2', } cinder::volume_type {'standard': backends => ['images', 'local-lvm']
Use three or more cinder-volume backends and assign them two to one type and the other to another
...
Requirements
- must configure as many supported backends as possible
- must be comptible with only defining one single backend
- must configure cinder volume_type example
- if types are default, must allow for a default type (so scheduler can consider multiple seperate providers equally)
