Administrators configure share types and make them
available to projects within an OpenStack cloud.
These share types will define capabilities to match
back-end storage pools that manila provisions shares
within. Administrators may want to limit share types
to specific Availability zones, given they may have
different classes of storage in different availability
zones in the cloud. A major use case of this is edge
computing, where, provisioning can be driven to specific
edge locations with the help of share types.
This commit will:
- Introduce 'availability_zones' as a new common share type
extra spec that is user visible when configured.
- In and beyond microversion 2.48, validate that the AZ
chosen in the POST /shares API is supported by the configured
availability zones for the share type being used.
- Share types can be filtered by AZs through extra-specs:
$ manila type-list --extra-specs availability_zone=nova
now gives you all types that explicitly (and implicitly)
are supported within the AZ 'nova'.
- Improve experimental APIs:
- Add validation of AZ to POST /share-replicas
- Add validation of AZ to POST /share-groups
- Add validation of AZ to
POST /shares/id {'action': 'migration_start'}
- Also fix old unit tests by using a helper method to
generate appropriate mock values.
