Wallaby Series Release Notes


Bug Fixes

  • Fixes an issue that could be caused by a user sending a malformed host notification missing host status. Such notification would block the host from being added back from maintenance until manual intervention or notification expiration. LP#1960619


Bug Fixes

  • Fixes “Instance stopping fails randomly due to already stopped instances”. LP#1980736


Bug Fixes

  • Fixes Masakari API to properly return error codes for invalid requests to the user instead of 500. LP#1932194


New Features

  • Sometimes, operators want to temporarily disable instance-ha function. This version adds ‘enabled’ to segment. If the segment ‘enabled’ value is set False, all notifications of this segment will be ignored and no recovery methods will execute.

Upgrade Notes

  • The default value of [oslo_policy] policy_file config option has been changed from policy.json to policy.yaml. Operators who are utilizing customized or previously generated static policy JSON files (which are not needed by default), should generate new policy files or convert them in YAML format. Use the oslopolicy-convert-json-to-yaml tool to convert a JSON to YAML formatted policy file in backward compatible way.

Deprecation Notes

  • Use of JSON policy files was deprecated by the oslo.policy library during the Victoria development cycle. As a result, this deprecation is being noted in the Wallaby cycle with an anticipated future removal of support by oslo.policy. As such operators will need to convert to YAML policy files. Please see the upgrade notes for details on migration of any custom policy files.

Bug Fixes

  • Fixes /v1/ API path which returned 404 ResourceNotFound preventing microversion discovery. LP#1685145

  • Allows segment description to contain new line characters. LP#1776385

  • Fixes Masakari Engine not to try to stop an already stopped instance and fail with 409 from Nova. LP#1782517

  • Adds reserved_host to all aggregates of the failing host, instead of just the first one. LP#1856164

  • Fixes Masakari Engine not to wait for timeout when it’s known that the evacuation has failed. LP#1859406 (This fix has already been included in the first Victoria release, 10.0.0, but it was not mentioned in the release notes previously.)

  • Fixes API microversion reporting to report the latest supported microversion. LP#1882516

  • Fixes an issue where a periodic task in Masakari Engine could loop forever querying Nova API following a failed evacuation. LP#1897888
