Current Series Release Notes

27.0.0-42

Upgrade Notes

  • The WSGI script cinder-wsgi has been removed. Deployment tooling should instead reference the Python module path for this service, cinder.wsgi.api, if their chosen WSGI server supports this (gunicorn, uWSGI) or implement a .wsgi script themselves if not (mod_wsgi).

Bug Fixes

  • The NetApp driver supports SMAS replication which on ONTAP is supported only from ONTAP 9.15.1. Additional validations are added to the driver to ensure ONTAP version checks and initialization of SnapMirror as part of creation of SMAS relationship.

  • Bug #2119123:

    Fix for NetApp Cinder Driver - Active Sync issues

  • Bug #2121812: Default node model to empty string in netapp driver.

  • NetApp driver bug #2125054: Fixed default_filter_fucntion for NetApp driver to maintain the consistency across different platforms like ONTAP9 and ASAr2.

    Admin can add a custom filter to impose the total_volumes limit for ONTAP backends like below. filter_function=capabilities.total_volumes < <max_volumes_admin_wants>

    Note: The admin needs to configure the scheduler_default_filters to include the DriverFilter as well under [DEFAULT] stanza as part of cinder.conf, please refer [1] for the default filter list.

  • Bug #2121361: Fixed issue when performing optimized image-volume clone using a backend with clone_across_pools capability enabled.

  • Bug #2056081: When cloning a volume from a source volume, we used the user ID of source volume user and not of the current user. Now we use the user ID as provided in the user context that initiated the operation.

  • HPE Nimble driver. Report thin provisioning capability correctly according to backend configuration.
