This is the second patch that implements the generic-volume-group
bluerpint. It adds the groups table and introduces create/delete/
update/list/show APIs for groups.
It depends on the first patch which adds group types and group specs:
https://review.openstack.org/#/c/320165/
Client side patch is here:
https://review.openstack.org/#/c/322627/
Current microversion is 3.13. The following CLI's are supported:
cinder --os-volume-api-version 3.13 group-create --name my_group
<group type uuid> <volume type uuid>
cinder --os-volume-api-version 3.13 group-list
cinder --os-volume-api-version 3.13 create --group-id <group uuid>
--volume-type <volume type uuid> <size>
cinder --os-volume-api-version 3.13 group-update <group uuid>
--name new_name description new_description
--add-volumes <uuid of volume to add>
--remove-volumes <uuid of volume to remove>
cinder --os-volume-api-version 3.13 group-show <group uuid>
cinder --os-volume-api-version 3.13 group-delete
--delete-volumes <group uuid>
