We are ecstatic to announce the release of: cinder 17.4.0: OpenStack Block Storage This release is part of the victoria stable release series. The source is available from: https://opendev.org/openstack/cinder Download the package from: https://tarballs.openstack.org/cinder/ Please report issues through: https://bugs.launchpad.net/cinder/+bugs For more details, please see below. 17.4.0 ^^^^^^ New Features ************ * Log a warning from the volume service when a volume driver's get_volume_stats() call takes a long time to return. This can help deployers troubleshoot a cinder-volume service misbehaving due to a driver/backend performance issue. Bug Fixes ********* * Fixed the schema validation for attachment create API to make instance uuid an optional field. It had mistakenly been defined as a required field when schema validation was added in an earlier release. Also updated the schema to allow specification of the "mode" parameter, which has been available since microversion >= 3.54, but which was not recognized as a legitimate request field. * Bug #1924643 (https://bugs.launchpad.net/cinder/+bug/1924643): Fixed the NetApp cinder driver sub-clone operation that might be used by extend operation in case the extended size is greater than the max LUN geometry.
