Newton Series Release Notes

14.2.7

New Features

  • The os_cinder role now provides for doing online data migrations once the db sync has been completed. The data migrations will not be executed until the boolean variable cinder_all_software_updated is true. This variable will need to be set by the playbook consuming the role.

14.2.4

New Features

  • New variables have been added to allow a deployer to customize a cinder systemd unit file to their liking.

  • The task dropping the cinder systemd unit files now uses the config_template action plugin allowing deployers access to customize the unit files as they see fit without having to load extra options into the defaults and polute the generic systemd unit file with jinja2 variables and conditionals.

14.2.1

New Features

  • Add support for the cinder v3 api. This is enabled by default, but can be disabled by setting the cinder_enable_v3_api variable to false.

  • For the os_cinder role, the systemd unit TimeoutSec value which controls the time between sending a SIGTERM signal and a SIGKILL signal when stopping or restarting the service has been reduced from 300 seconds to 120 seconds. This provides 2 minutes for long-lived sessions to drain while preventing new ones from starting before a restart or a stop. The RestartSec value which controls the time between the service stop and start when restarting has been reduced from 150 seconds to 2 seconds to make the restart happen faster. These values can be adjusted by using the cinder_*_init_config_overrides variables which use the config_template task to change template defaults.

Deprecation Notes

  • The variables cinder_sigkill_timeout and cinder_restart_wait have been deprecated and will be removed in Pike.

14.0.8

Upgrade Notes

  • The global override cinder_nfs_client is replaced in favor of fully supporting multi backends configuration via the cinder_backends stanza.

Deprecation Notes

14.0.7

New Features

  • Additional volume-types can be created by defining a list named extra_volume_types in the desired backend of the variable(s) cinder_backends

  • Deployers can now define the varible cinder_qos_specs to create qos specs and assign those specs to desired cinder volume types.

14.0.2

New Features

  • Deployers can now define the override cinder_rpc_executor_thread_pool_size which defaults to 64

  • Deployers can now define the override cinder_rpc_response_timeout which defaults to 60

Upgrade Notes

  • The variables cinder_requirements_git_repo and cinder_requirements_git_install_branch have been removed in favour of using the URL/path to the upper-constraints file using the variable pip_install_upper_constraints instead.

14.0.0

New Features

  • The os_cinder role now supports Ubuntu 16.04.

  • CentOS7/RHEL support has been added to the os_cinder role.

  • The os_cinder role now supports the ability to configure whether apt/yum tasks install the latest available package, or just ensure that the package is present. The default action is to ensure that the latest package is present. The action taken may be changed to only ensure that the package is present by setting cinder_package_state to present.

Upgrade Notes

  • Installation of cinder and its dependent pip packages will now only occur within a Python virtual environment. The cinder_venv_enabled and cinder_venv_bin variables have been removed.

  • The variable cinder_apt_packages has been renamed to cinder_distro_packages.

  • The variable cinder_volume_apt_packages has been renamed to cinder_volume_distro_packages.

  • The variable cinder_lvm_volume_apt_packages has been renamed to cinder_lvm_volume_distro_packages.

  • The os_cinder role always checks whether the latest package is installed when executed. If a deployer wishes to change the check to only validate the presence of the package, the option cinder_package_state should be set to present.

  • The database create and user creates have been removed from the os_cinder role. These tasks have been relocated to the playbooks.
