Current Series Release Notes

New Features

  • Enabled horizon to make use of cinder’s feature to backup up snapshots of block storage volumes.

  • [blueprint multi-Attached-volume-support] Horizon now support Multi-Attached volume. User is now able to attach a volume to multiple instances. The ability to attach a volume to multiple host/servers requires that the volume type includes an extra-spec capability setting of multiattach=<is> True. Horizon automatically detects and enable multi-attach-volume feature.

    API restrictions:

    Multiattach capable volumes can only be attached with nova API microversion 2.60 or later.

Upgrade Notes

  • Cinder consistency group support in horizon has been dropped in Train release. It was deprecated in Pike release in Cinder and deprecated in Stein release in Horizon. The feature is superseded by the generic group feature and horizon provides full support of the generic group.

  • policy.json files for Cinder, Keystone Neutron and Nova are generated according to Policy file maintenance. Keystone changes to policy rules <>__, are not compatible with the Horizon so we keystone_policy.json is not updated. Please, be sure that new Keystone policies are compatible with your deployment before syncing them.

  • Deprecated config option ENABLE_FLAVOR_EDIT is removed.

  • Deprecated SHOW_KEYSTONE_V2_RC since Stein release is removed.

  • python-cinderclient >=4.0.1 is now required to fix bug 1824017. Cinder API 3.55 or later does not accept additional properties but python-cinderclient older than 4.0.0 sends additional properties like used_id, status and so on. Horizon uses Cinder API 3.58 to create a volume, and this means the volume creation fails if python-cinderclient <4.0.0 is used. To handle this, the minimum requirement of python-cinderclient was bumped to 4.0.1.

Other Notes

  • The default visibility when creating new images has been changed from private to shared to bring it inline with the default changing in Glance since Image API v2.5.
