Branches in Extended Maintenance will not be released, but they can still
accept backports of bugfixes. We may want to include release notes for these
fixes, even if they will not be included in an official release. In this case,
in addition to backporting the release note, you will need to manually refresh
the static page so those new notes will show up under a development release
version in the generated output.
To regenerate the static landing pages in this case, run the following commands
from the root of the openstack/cinder repo::
tox -e releasenotes --notest
.tox/releasenotes/bin/reno report \
--title "$SERIES Series Release Notes" \
--branch "stable/$series" | \
sed 's/^ *$//g' > "releasenotes/source/$series.rst"
In this example, ``$SERIES`` would be the title-cased series name (i.e. Rocky),
and $series would be the series name in lower case (i.e. rocky).
This should replace the static release note page. That page should then be
added to the commit and included as part of the review.

3PAR driver adds the config option `hpe3par_target_nsp` that can be
set to the 3PAR backend to use when multipath is not enabled and
the Fibre Channel Zone Manager is not used.

- NetApp iSCSI drivers no longer use the discovery mechanism for multipathing
and they always return all target/portals when attaching a volume. Thanks
to this, volumes will be successfully attached even if the target/portal
selected as primary is down, this will be the case for both, multipath and
single path connections.

Upgrade Notes
-------------
.. releasenotes/notes/bug-1805550-default-policy-file-db15eaa76fefa115.yaml @ b'd07abe397c5bdfb45a82150fb7e1a9efaf21ce42'
- 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
---------
.. releasenotes/notes/bug-1790141-vmax-powermaxos-upgrade-fix-4c76186cfca66790.yaml @ b'f9bfbec2b5e35d1ae8df51229dd4105221b2761f'
- 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.
.. releasenotes/notes/bug-1799221-fix-truncated-volumes-in-case-of-glance-errors-6cae19218249c3cf.yaml @ b'bf89f76fb1b7a52299c17467106018eae01608e8'
- 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>`_).
.. releasenotes/notes/bug-reno-69539ecb9b0b5464.yaml @ b'6ceed81d4b25978ac64bf36afa45c021ef95d02f'
- The Solidfire cinder driver has been fixed to ensure delete happens
on the correct volume.

- The ``cinder-manage db online_data_migrations`` command now returns exit
status 2 in the case where some migrations failed (raised exceptions) and
no others were completed successfully from the last batch attempted. This
should be considered a fatal condition that requires intervention. Exit
status 1 will be returned in the case where the ``--max-count`` option was
used and some migrations failed but others succeeded (updated at least one
row), because more work may remain for the non-failing migrations, and
their completion may be a dependency for the failing ones. The command
should be reiterated while it returns exit status 1, and considered
completed successfully only when it returns exit status 0.

- Now scheduler plugins are aware of operation type via ``operation`` attribute in
RequestSpec dictionary, plugins can support backend filtering according to backend
status as well as operation type. Current possible values for ``operation`` are:
- create_volume
- extend_volume
- create_snapshot

- Added boolean conf option 'split_loggers' in [default] section of
cinder.conf to `enable split logging`_ functionality. The default
value of split_loggers option is set to False. Operator can set it's
value to True to split HTTP content into subloggers to allow for
fine-grained control of what is logged and how. This new config option
'split_loggers' should be enabled only when keystoneauth log level is
set to DEBUG in 'default_log_levels' config option.
.. _`enable split logging`: https://docs.openstack.org/keystoneauth/latest/using-sessions.html#logging
.. releasenotes/notes/bp-nvmeof-lvm-target-b7771955b426abe7.yaml @ b'8d7e131c587f31d85c76f990998d411af490554f'
- A new target, NVMET, is added for the LVM driver over RDMA,
it allows cinder to use nvmetcli in order to create/delete
subsystems on attaching/detaching an LVM volume to/from an
instance.
.. releasenotes/notes/bug-1686745-e8f1569455f998ba.yaml @ b'abca1abc7b01fc1d85af8b9cfa5b646abafc9d4a'
- Add support to force detach a volume from all hosts on 3PAR.
.. releasenotes/notes/capacity-based-qos-9f5d174658a40bd5.yaml @ b'29d2090aef7b31df23ca846d365c6d21957486ba'
- Cinder now allows for capacity based QoS which can be useful in environments where storage performance scales with consumption (such as RBD backed storage). The newly added QoS specs are `read_iops_sec_per_gb`, `write_iops_sec_per_gb`, `total_iops_sec_per_gb`, `read_bytes_sec_per_gb`, `write_bytes_sec_per_gb` and `total_bytes_sec_per_gb`. These values will be multiplied by the size of the volume and passed to the consumer.
For example, setting `total_iops_sec_per_gb` to 30 and setting `total_bytes_sec_per_gb` to `1048576` (1MB) then creating a 100 GB volume with that QoS will result in a volume with 3,000 total IOPs and 100MB/s throughput limit.
.. releasenotes/notes/capacity-based-qos-minimum-values-b24a5f49c986f11d.yaml @ b'37f2bdcdec85f27651b91a9a2d0fddb66e7bfe8a'
- Cinder now allows for a minimum value when using the capacity based QoS in order to make sure small volumes can get a minimum allocation for them to be usable.
The newly added QoS specs are `read_iops_sec_per_gb_min`, `write_iops_sec_per_gb_min`, `total_iops_sec_per_gb_min`, `read_bytes_sec_per_gb_min`, `write_bytes_sec_per_gb_min` and `total_bytes_sec_per_gb_min`
.. releasenotes/notes/cheesecake-promotion-30a3336fb911c3ad.yaml @ b'df81b59f9d1f70dcde002eb9252c55e46d77a5c0'
- A new cinder-manage command, reset_active_backend, was added to promote a
failed-over backend participating in replication. This allows you to
reset a backend without manually editing the database. A backend
undergoing promotion using this command is expected to be in a disabled
and frozen state. Support for both standalone and clustered backend
configurations are supported.
.. releasenotes/notes/dell-emc-sc-api-timeouts-ce8d166e1847ea94.yaml @ b'1d6ad6ef179f465289c95b5f45ac79b0f03e0866'
- Added dell_api_async_rest_timeout option to the Dell EMC SC driver. This is the timeout used for asynchronous REST calls to the Dell EMC SC REST API. Default is 15 seconds.
.. releasenotes/notes/dell-emc-sc-api-timeouts-ce8d166e1847ea94.yaml @ b'1d6ad6ef179f465289c95b5f45ac79b0f03e0866'
- Added dell_api_sync_rest_timeout option to the Dell EMC SC driver. This is the timeout used for synchronous REST calls to the Dell EMC SC REST API. Default is 30 seconds.
.. releasenotes/notes/dell-emc-sc-mult-attach-d09cfd06ee8db8da.yaml @ b'2e82f0de90d077f7d87353b59c14f69bff3dbaa5'

anything other than `restoring` using `cinder backup-reset-state`.
.. releasenotes/notes/feature-cross-az-backups-6b68c4c4456f2fd7.yaml @ b'5feaf74ccf10148859e206ce21bfd54dec2c1c16'
- Cinder backup creation can now (since microversion 3.51) receive the
availability zone where the backup should be stored.
.. releasenotes/notes/feature-multi-process-backup-8cf5ad5a0cf9b2d5.yaml @ b'373b52404151d80e83004a37d543f825846edea1'
- Cinder backup now supports running multiple processes to make the most of
the available CPU cores. Performance gains will be significant when
running multiple concurrent backups/restores with compression. The number
of processes is set with `backup_workers` configuration option.
.. releasenotes/notes/feature-rbd-exclusive-pool-a9bdebdeb1f0bf37.yaml @ b'f33baccc3544cbda6cd5908328a56096046657ed'
- When using the RBD pool exclusively for Cinder we can now set
`rbd_exclusive_cinder_pool` to `true` and Cinder will use DB information
to calculate provisioned size instead of querying all volumes in the
backend, which will reduce the load on the Ceph cluster and the volume
service.
.. releasenotes/notes/google-auth-for-gcs-backup-1642cd0e741fbdf9.yaml @ b'79d7a4e8da6f1118b5c235928876cf78085f4332'

- Dell EMC ScaleIO has been renamed to Dell EMC VxFlex OS.
Documentation for the driver can be found under the new name.
The driver maintains full backwards compatability with prior
ScaleIO releases and no configuration changes are needed upon
upgrade to the new version of the driver.

- The SMBFS driver now supports the 'snapshot attach' feature. Special care
must be taken when attaching snapshots though, as writing to a snapshot
will corrupt the differencing image chain.
.. releasenotes/notes/storwize-dr-pool-support-52db3a95e54aef88.yaml @ b'822fb701de48d30e662b5f16270b3c38e8703151'

- Now availability zone is supported in volume type as below.
* ``RESKEY:availability_zones`` now is a reserved spec key for AZ volume type,
and administrator can create AZ volume type that includes AZ restrictions
by adding a list of Az's to the extra specs similar to:
``RESKEY:availability_zones: az1,az2``.
* Extra spec ``RESKEY:availability_zones`` will only be used for filtering backends
when creating and retyping volumes.
* Volume type can be filtered within extra spec: /types?extra_specs={"key":"value"}
since microversion "3.52".

- Added image signature verification support when creating volume from image. This depends on signature metadata from glance. This feature is turned on by default, administrators can change behaviour by updating option ``verify_glance_signatures``. Also, an additional image metadata ``signature_verified`` has been added to indicate whether signature verification was performed during creating process.

- Backup service to driver mapping is removed. If you use old values like
'cinder.backup.services.swift' or 'cinder.backup.services.ceph' it should
be changed to 'cinder.backup.drivers.swift' or 'cinder.backup.drivers.ceph'
accordingly to get your backup service working.

- On offline upgrades, due to the rolling upgrade mechanism we need to restart the cinder services twice to complete the installation just like in the rolling upgrades case. First you stop the cinder services, then you upgrade them, you sync your DB, then you start all the cinder services, and then you restart them all. To avoid this last restart we can now instruct the DB sync to bump the services after the migration is completed, the command to do this is `cinder-manage db sync --bump-versions`

- Fix a quota usage error triggered by a non-admin user backing up an
in-use volume. The forced backup uses a temporary volume, and quota
usage was incorrectly updated when the temporary volume was deleted
after the backup operation completed.

- Volume "force delete" was introduced with the 3.23 API microversion,
however the check for in the service was incorrectly looking for
microversion 3.2. That check has now been fixed. It is possible that an API
call using a microversion below 3.23 would previously work for this call,
which will now fail. This closes
`bug #1783028 <https://bugs.launchpad.net/cinder/+bug/1783028>`_.

- When encryption keys based on the ConfKeyManager's fixed_key are migrated
to Barbican, ConfKeyManager keys stored in the Backup table are included
in the migration process.

- Storwize SVC Driver: Fixes `bug 1749687
<https://bugs.launchpad.net/cinder/+bug/1749687>`__
previously lsvdisk() was called separately for every
'in-use' volume in order to check if the volume exists
on the storage.
In order to avoid problem of too long driver initialization
now lsvdisk() is called once per pool.

- Fixed bug #1783582, where calls to os-force_detach were failing on NetApp
ONTAP iSCSI/FC drivers.

- Fixed bug #1731474 on NetApp Data ONTAP driver that was causing LUNs to be created
with larger size than requested. This fix requires version 9.1 of ONTAP
or later.

- Added a new optional cache of volumes generated from snapshots for the
Quobyte backend. Enabling this cache speeds up creation of multiple
volumes from a single snapshot at the cost of a slight increase in
creation time for the first volume generated for this given snapshot.
The ``quobyte_volume_from_snapshot_cache`` option is off by default.

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

- RBD driver can have bottlenecks if too many slow operations are happening at the same time (for example many huge volume deletions), we can now use the `backend_native_threads_pool_size` option in the RBD driver section to resolve the issue.

- Added schema validation support using jsonschema `[json-schema-validation]`_
for all supported v3 APIs.
Following APIs were accepting boolean parameters with leading and trailing
white spaces (for e.g. " true "). But now with schema validation support,
all these boolean parameters henceforth will not accept leading and trailing
whitespaces to maintain consistency.
* Generic volume groups:
* delete group: "POST /v3/{project_id}/groups/{group_id}/action"
* failover replication: "POST /v3/{project_id}/groups/{group_id}/action"
* Volume Snapshots:
* create a snapshot: "POST /v3/{project_id}/snapshots"
* Volume_actions:
* set bootable: "POST /v3/{project_id}/volumes/{volume_id}/action"
* volume readonly update: "POST /v3/{project_id}/volumes/{volume_id}/action"
