Ocata Series Release Notes¶

15.1.6¶

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.

The ability to disable the certificate validation when checking and interacting with the internal cinder endpoint has been implemented. In order to do so, set the following in /etc/openstack_deploy/user_variables.yml.
```
cinder_service_internaluri_insecure: yes
```

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.

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.

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

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

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.

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

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.

The cinder project removed the shred value for the volume_clear option. The default for the os_cinder OpenStack-Ansible role has changed to zero.
