Nova will now internally use a new flow for new volume attachments when:
|
|
|
|
* All *nova-compute* services are upgraded
|
|
* The *block-storage* 3.44 API microversion is available
|
|
|
|
This change should be transparent to end users and does not affect existing
|
|
volume attachments. Also, this does not affect how new volumes are created
|
|
and attached during boot-from-volume when the
|
|
``block_device_mapping_v2.source_type`` is ``blank``, ``image`` or
|
|
``snapshot`` and the ``block_device_mapping_v2.destination_type`` is
|
|
``volume``.
|
|
|
|
The motivation behind these changes are:
|
|
|
|
* Track volume attachment state in the block storage service rather than
|
|
the compute service (separation of duties, simplicity, etc)
|
|
* Removal of technical debt from the compute service long-term
|
|
* Enable a foundation on which to build support for multi-attach volumes
