Generic volume groups (groups)
|
|
==============================
|
|
|
|
Generic volume groups enable you to create a group of volumes and
|
|
manage them together.
|
|
|
|
How is generic volume groups different from consistency groups?
|
|
Currently consistency groups in cinder only support consistent group
|
|
snapshot. It cannot be extended easily to serve other purposes. A project
|
|
may want to put volumes used in the same application together in a group
|
|
so that it is easier to manage them together, and this group of volumes
|
|
may or may not support consistent group snapshot. Generic volume group
|
|
is introduced to solve this problem. By decoupling the tight relationship
|
|
between the group construct and the consistency concept, generic volume
|
|
groups can be extended to support other features in the future.
|
|
|
|
|
|
List groups

~~~~~~~~~~~
|
|
|
|
.. rest_method:: GET /v3/{project_id}/groups
|
|
|
|
Lists groups. Since v3.31 if non-admin users specify
|
|
invalid filters in the url, API will return bad request.
