Zed Series Release Notes

4.1.1-3

New Features

  • The RBD driver now moves images to the trash if they cannot be deleted immediately due to having snapshots. This fixes the long-standing issue where base images are unable to be deleted until/unless all snapshots of it are also deleted. Moving the image to the trash allows Glance to proceed with the deletion of the image (as far as it is concerned), mark the RBD image for deletion, which will happen once the last snapshot that uses it has been deleted.

4.1.1

Security Issues

  • Cinder glance_store driver: in order to avoid a situation where a leftover device could be mapped to a different volume than the one intended, the cinder glance_store driver now instructs the os-brick library to force detach volumes, which ensures that devices are removed from the host.

    See Bug #2004555 for more information about this issue.

4.1.0

Bug Fixes

  • Now the project_domain_name parameter and the user_domain_name parameter are properly used by swift backends. Previously these two parameters were ignored and the *_domain_id parameters should be set to use a keystone domain different from the default one.

4.0.1

New Features

  • When using the cinder backend, a custom os-brick file lock location can be specified using the lock_path configuration option in the [os_brick] configuration section. Helpful when deploying on the same host as the Cinder service.

Upgrade Notes

  • When running Cinder and Glance with Cinder backend on the same host an os-brick shared location can be configured using the lock_path in the [os_brick] configuration section.

4.0.0

Upgrade Notes

  • Python 3.6 & 3.7 support has been dropped. The minimum version of Python now supported is Python 3.8.

Bug Fixes

  • Bug #1970698: Cinder: Fixed exception logging when the image create operation fails due to failing to attach volume to glance host.

  • Bug #1969373: Cinder Driver: Correct the retry interval from fixed 1 second to exponential backoff for attaching a volume during image create/save operation.
