Wallaby Series Release Notes¶
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
Fixes “Instance stopping fails randomly due to already stopped instances”. LP#1980736
Fixes Masakari API to properly return error codes for invalid requests to the user instead of 500. LP#1932194
Allows to use system-scoped tokens when contacting Nova. Blueprint support-nova-system-scope-policies
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.
The default value of
[oslo_policy] policy_fileconfig option has been changed from
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.
Use of JSON policy files was deprecated by the
oslo.policylibrary 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.
