12.0.5
^^^^^^


Known Issues
************

* Multiattach support is disabled for the LVM driver when using the
  LIO iSCSI target.  This functionality will be fixed in a later
  release.


Upgrade Notes
*************

* Beginning with Cinder version 12.0.0, as part of the Queens
  release "policies  in code" community effort, Cinder has had the
  ability to run without a policy file because sensible default values
  are specified in the code.  Customizing the policies in effect at
  your site, however, still requires a policy file.  The default
  location of this file has been "/etc/cinder/policy.json" (although
  the documentation has indicated otherwise).  With this release, the
  default location of this file is changed to
  "/etc/cinder/policy.yaml".

  Some points to keep in mind:

  * The policy file to be used may be specified in the
    "/etc/cinder/cinder.conf" file in the "[oslo_policy]" section as
    the value of the "policy_file" configuration option. That way
    there's no question what file is being used.

  * To find out what policies are available and what their default
    values are, you can generate a sample policy file.  To do this,
    you must have a local copy of the Cinder source code repository.
    From the top level directory, run the command:

       tox -e genpolicy

    This will generate a file named "policy.yaml" in the "etc/cinder"
    directory of your checked-out Cinder repository.

  * The sample file is YAML (because unlike JSON, YAML allows
    comments). If you prefer, you may use a JSON policy file.

  * Beginning with Cinder 12.0.0, you only need to specify policies
    in your policy file that you want to **differ** from the default
    values. Unspecified policies will use the default values *defined
    in the code*. Given that a default value *must* be specified *in
    the code* when a new policy is introduced, the "default" policy,
    which was formerly used as a catch-all for policy targets that
    were not defined elsewhere in the policy file, has no effect.  We
    mention this because an old upgrade strategy was to use the policy
    file from the previous release with ""default": "role:admin"" (or
    ""default": "!"") so that newly introduced actions would be
    blocked from end users until the operator had time to assess the
    implications of exposing these actions.  This strategy no longer
    works.  Hopefully this isn't a problem because we're defining
    sensible defaults in the code.  It would be a good idea, however,
    to generate the sample policy file with each release (see
    instructions above) to verify this for yourself.


Bug Fixes
*********

* PowerMax driver - Workload support was dropped in ucode 5978. If a
  VMAX All Flash array is upgraded to 5978 or greater and existing
  volume types leveraged workload e.g. DSS, DSS_REP, OLTP and
  OLTP_REP, certain operations will no longer work and the volume type
  will be unusable. This fix addresses these issues and fixes problems
  with using old volume types with workloads included in the volume
  type pool_name.

* Fixed a bug which could create volumes with invalid content in
  case of unhandled errors from glance client (Bug #1799221
  (https://bugs.launchpad.net/cinder/+bug/1799221)).

* The Solidfire cinder driver has been fixed to ensure delete
  happens on the correct volume.

* Cinder will now consume quota when importing new backup resource.

* Fixes a bug in NetApp SolidFire where the deletion of group
  snapshots was failing.

* Fixes force_detach behavior for volumes in NetApp SolidFire
  driver.

* Updated the parameter storwzie_preferred_host_site from StrOpt to
  DictOpt in cinder back-end configuration, and removed it from volume
  type configuration.
