10.0.8-20
=========

.. _Ocata Series Release Notes_10.0.8-20_stable_ocata_New Features:

New Features
------------

.. releasenotes/notes/feature-rbd-exclusive-pool-a9bdebdeb1f0bf37.yaml @ b'b1a0d62f357e431a6b74d38440a8392de972b824'

- 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/generic-group-quota-manage-support-559629ad07a406f4.yaml @ b'492cf46f63c829ec722c0b8fb06de678e85afc5e'

- Generic group is added into quota management.

.. releasenotes/notes/unity-remove-empty-host-17d567dbb6738e4e.yaml @ b'9773f963fea7e8a7033a047fda8967259ef4f99f'

- Dell EMC Unity Driver: Adds support for removing empty host. The new option
  named `remove_empty_host` could be configured as `True` to notify Unity
  driver to remove the host after the last LUN is detached from it.

.. releasenotes/notes/vnx-add-force-detach-support-26f215e6f70cc03b.yaml @ b'39f1f020f46eaf57ed106648047da4f318c37d5d'

- Add support to force detach a volume from all hosts on VNX.


.. _Ocata Series Release Notes_10.0.8-20_stable_ocata_Known Issues:

Known Issues
------------

.. releasenotes/notes/feature-rbd-exclusive-pool-a9bdebdeb1f0bf37.yaml @ b'b1a0d62f357e431a6b74d38440a8392de972b824'

- If RBD stats collection is taking too long in your environment maybe even
  leading to the service appearing as down you'll want to use the
  `rbd_exclusive_cinder_pool = true` configuration option if you are using
  the pool exclusively for Cinder and maybe even if you are not and can live
  with the innacuracy.


.. _Ocata Series Release Notes_10.0.8-20_stable_ocata_Bug Fixes:

10.0.8
======

.. _Ocata Series Release Notes_10.0.8_stable_ocata_Security Issues:

Security Issues
---------------

.. releasenotes/notes/scaleio-zeropadding-a0273c56c4d14fca.yaml @ b'2dc52153215bb6a37532a959c5c98239be21bb56'

- Removed the ability to create volumes in a ScaleIO Storage Pool that has
  zero-padding disabled. A new configuration option
  ``sio_allow_non_padded_volumes`` has been added to override this new
  behavior and allow unpadded volumes, but should not be enabled if multiple
  tenants will utilize volumes from a shared Storage Pool.


.. _Ocata Series Release Notes_10.0.8_stable_ocata_Bug Fixes:

Bug Fixes
---------

.. releasenotes/notes/bug-1690954-40fc21683977e996.yaml @ b'dbca62c207d63bbc192acf75ae39c6b56702295a'

.. releasenotes/notes/bug-1762424-f76af2f37fe408f1.yaml @ b'ee330b9a27cc49b5566a2df878a6da51e701f83c'

- NetApp ONTAP (bug 1762424): Fix ONTAP NetApp driver not being able to extend
  a volume to a size greater than the corresponding LUN max geometry.

.. releasenotes/notes/fix-abort-backup-df196e9dcb992586.yaml @ b'f3aa39f21505dddaab592a85648678d628f5616e'

- We no longer leave orphaned chunks on the backup backend or leave a
  temporary volume/snapshot when aborting a backup.

.. releasenotes/notes/netapp_fix_svm_scoped_permissions.yaml @ b'd67448fdad668a35c5c35a5a06d2ac2af5b26bcd'

- NetApp cDOT block and file drivers have improved support for SVM scoped user accounts. Features not supported for SVM scoped users include QoS, aggregate usage reporting, and dedupe usage reporting.


.. _Ocata Series Release Notes_10.0.7_stable_ocata:

10.0.7
======

.. _Ocata Series Release Notes_10.0.7_stable_ocata_New Features:

New Features
------------

.. releasenotes/notes/k2-disable-discovery-bca0d65b5672ec7b.yaml @ b'c3464ac5cb523fecb3c265e1f1ed26831507d126'

- Kaminario K2 iSCSI driver now supports non discovery multipathing (Nova and
  Cinder won't use iSCSI sendtargets) which can be enabled by setting
  `disable_discovery` to `true` in the configuration.

.. releasenotes/notes/rbd-stats-report-0c7e803bb0b1aedb.yaml @ b'69a79e38afbdc67f61568c0b82cf6d06ca304e56'

- RBD driver supports returning a static total capacity value instead of a
  dynamic value like it's been doing.  Configurable with
  `report_dynamic_total_capacity` configuration option.


.. _Ocata Series Release Notes_10.0.7_stable_ocata_Known Issues:

Known Issues
------------

.. releasenotes/notes/k2-non-unique-fqdns-b62a269a26fd53d5.yaml @ b'caceaa52a7070548b7b42df877e23bc4d3845def'

- Kaminario K2 now supports networks with duplicated FQDNs via configuration
  option `unique_fqdn_network` so attaching in these networks will work
  (bug #1720147).


.. _Ocata Series Release Notes_10.0.7_stable_ocata_Upgrade Notes:

Upgrade Notes
-------------

.. releasenotes/notes/bug-1714209-netapp-ontap-drivers-oversubscription-issue-c4655b9c4858d7c6.yaml @ b'83a849a78c93ad7a1a7f2c9c0cd3b7ae08a2ff32'

- If using the NetApp ONTAP drivers (7mode/cmode), the configuration value for "max_over_subscription_ratio" may need to be increased to avoid scheduling problems where storage pools that previously were valid to schedule new volumes suddenly appear to be out of space to the Cinder scheduler. See documentation `here <https://docs.openstack .org/cinder/latest/admin/blockstorage-over-subscription.html>`_.

.. releasenotes/notes/rbd-stats-report-0c7e803bb0b1aedb.yaml @ b'69a79e38afbdc67f61568c0b82cf6d06ca304e56'

- RBD/Ceph backends should adjust `max_over_subscription_ratio` to take into
  account that the driver is no longer reporting volume's physical usage but
  it's provisioned size.


.. _Ocata Series Release Notes_10.0.7_stable_ocata_Bug Fixes:

Bug Fixes
---------

.. releasenotes/notes/bug-1632333-netapp-ontap-copyoffload-downloads-glance-image-twice-08801d8c7b9eed2c.yaml @ b'6d59c490c262d7634af5b2e03149c9f028f4d81c'

- Fixed bug 1632333 with the NetApp ONTAP Driver. Now the copy offload method is invoked
  early to avoid downloading Glance images twice.

.. releasenotes/notes/bug-1714209-netapp-ontap-drivers-oversubscription-issue-c4655b9c4858d7c6.yaml @ b'83a849a78c93ad7a1a7f2c9c0cd3b7ae08a2ff32'

- The ONTAP drivers ("7mode" and "cmode") have been fixed to not report consumed space as "provisioned_capacity_gb". They instead rely on the cinder scheduler's calculation of "provisioned_capacity_gb". This fixes the oversubscription miscalculations with the ONTAP drivers. This bugfix affects all three protocols supported by these drivers (iSCSI/FC/NFS).

.. releasenotes/notes/dell-emc-sc-bugfix-1756914-ffca3133273040f6.yaml @ b'd2bff999dbf9fdf48e4b1f4c402217ceb97bf6a0'

- Dell EMC SC driver correctly returns initialize_connection data when more than one IQN is attached to a volume. This fixes some random Nova Live Migration failures where the connection information being returned was for an IQN other than the one for which it was being requested.

.. releasenotes/notes/netapp-ontap-use_exact_size-d03c90efbb8a30ac.yaml @ b'013d6183c434ec05a11115e603f02cf6e57a85b1'

- 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.

.. releasenotes/notes/ps-duplicate-ACL-5aa447c50f2474e7.yaml @ b'c96512aab0ee00201e26b0efa9c87c7f62fd463e'

- Dell EMC PS Series Driver code was creating duplicate ACL records during live migration. Fixes the initialize_connection code to not create access record for a host if one exists previously. This change fixes bug 1726591.

.. releasenotes/notes/ps-extend_volume-no-snap-8aa447c50f2475a7.yaml @ b'09b1b1351901b5cf042b2a59624751451707c87a'

- Dell EMC PS Series Driver was creating unmanaged snapshots when extending volumes. Fixed it by adding the missing no-snap parameter. This change fixes bug 1720454.

.. releasenotes/notes/ps-optimize-parsing-8aa447c50f2474c7.yaml @ b'047c3f87b590ea2d627692d05347fcb49c060bab'

- Dell EMC PS Series Driver code reporting volume stats is now optimized to return the information earlier and accelerate the process. This change fixes bug 1661154.

.. releasenotes/notes/ps-over-subscription-ratio-cal-8aa447c50f2474a8.yaml @ b'e205ab8dc7ac73d182958e60b6b9a9cb7b54601d'

- Dell EMC PS Driver stats report has been fixed, now reports the
  `provisioned_capacity_gb` properly. Fixes bug 1719659.

.. releasenotes/notes/rbd-stats-report-0c7e803bb0b1aedb.yaml @ b'69a79e38afbdc67f61568c0b82cf6d06ca304e56'

- RBD stats report has been fixed, now properly reports
  `allocated_capacity_gb` and `provisioned_capacity_gb` with the sum of the
  sizes of the volumes (not physical sizes) for volumes created by Cinder and
  all available in the pool respectively.  Free capacity will now properly
  handle quota size restrictions of the pool.

- The IBM_Storage driver has been open sourced. This means that there is no
  more need to download the package from the IBM site. The only requirement
  remaining is to install pyxcli, which is available through pypi::

      ``sudo pip install pyxcli``

.. releasenotes/notes/capacity-headroom-4b07701f1df9e5c4.yaml @ b'b67a416bb94bc0f2e64fc896e1c04581956f777d'

- The SolidFire driver will recognize 4 new QoS spec keys to allow an administrator to specify QoS settings which are scaled by the size of the volume. 'ScaledIOPS' is a flag which will tell the driver to look for 'scaleMin', 'scaleMax' and 'scaleBurst' which provide the scaling factor from the minimum values specified by the previous QoS keys ('minIOPS', 'maxIOPS', 'burstIOPS'). The administrator must take care to assure that no matter what the final calculated QoS values follow minIOPS <= maxIOPS <= burstIOPS. A exception will be thrown if not. The QoS settings are also checked against the cluster min and max allowed and truncated at the min or max if they exceed.

.. releasenotes/notes/vnx-async-migration-support-3c449139bb264004.yaml @ b'6ccfcafd45c445bc48593a310a3649e18c8b8a51'

- VNX cinder driver now supports async migration during volume cloning. By default, the cloned volume will be available after the migration starts in the VNX instead of waiting for the completion of migration. This greatly accelerates the cloning process. If user wants to disable this, he could add ``--metadata async_migrate=False`` when creating volume from source volume/snapshot.

- With the Dell SC Cinder Driver if a volume is retyped to a new storage profile all volumes created via snapshots from this volume will also change to the new storage profile.

.. releasenotes/notes/Dell-SC-Retype-Limitations-74f4b5f6a94ffe4f.yaml @ b'c514b25b0783769d5349b0a34880545c54e1ca4c'

- With the Dell SC Cinder Driver retyping from one replication type to another type (ex. regular replication to live volume replication) is not supported.

- Dell SC Cinder driver has limited support in a failed over state so thaw_backend has been implemented to reject the thaw call when in such a state.


.. _Ocata Series Release Notes_10.0.0_stable_ocata_Upgrade Notes:

Upgrade Notes
-------------

.. releasenotes/notes/add-suppress-lvm-fd-warnings-option.402bebc03b0a9f00.yaml @ b'055ec1ce73ca55c463481c349b42dee66e5e86d6'

- In certain environments (Kubernetes for example) indirect calls to the LVM
  commands result in file descriptor leak warning messages which in turn cause
  the process_execution method to raise and exception.

  To accommodate these environments, and to maintain backward compatibility
  in Newton we add a ``lvm_suppress_fd_warnings`` bool config to the LVM driver.
  Setting this to True will append the LVM env vars to include the variable
  ``LVM_SUPPRESS_FD_WARNINGS=1``.

  This is made an optional configuration because it only applies to very specific
  environments.  If we were to make this global that would require a rootwrap/privsep
  update that could break compatibility when trying to do rolling upgrades of the
  volume service.

.. releasenotes/notes/bp-open-src-ibm-storage-driver-d17808e52aa4eacb.yaml @ b'c5630ce51dd7b3902bbf204707a3ae6674884109'

- Previous installations of IBM Storage must be un-installed first and the
  new driver should be installed on top. In addition the cinder.conf values
  should be updated to reflect the new paths. For example the proxy setting
  of ``storage.proxy.IBMStorageProxy`` should be updated to
  ``cinder.volume.drivers.ibm.ibm_storage.proxy.IBMStorageProxy``.

.. releasenotes/notes/cinder-api-middleware-remove-deprecated-option-98912ab7e8b472e8.yaml @ b'c5630ce51dd7b3902bbf204707a3ae6674884109'

- Removed deprecated option ``osapi_max_request_body_size``.

.. releasenotes/notes/cinder-manage-db-online-schema-migrations-d1c0d40f26d0f033.yaml @ b'c5630ce51dd7b3902bbf204707a3ae6674884109'

- To get rid of long running DB data migrations that must be run offline, Cinder will now be able to execute them online, on a live cloud. Before upgrading from Ocata to Pike, operator needs to perform all the Newton data migrations. To achieve that he needs to perform ``cinder-manage db online_data_migrations`` until there are no records to be updated. To limit DB performance impact migrations can be performed in chunks limited by ``--max_number`` option. If your intent is to upgrade Cinder in a non-live manner, you can use ``--ignore_state`` option safely. Please note that finishing all the Newton data migrations will be enforced by the first schema migration in Pike, so you won't be able to upgrade to Pike without that.

.. releasenotes/notes/datera-2.3-driver-update-12d0221fd4bb9fb0.yaml @ b'9a8dc08346964a58023992eb1d7b00cb0e4e7679'

- The Cinder database can now only be upgraded from changes since the Liberty release. In order to upgrade from a version prior to that, you must now upgrade to at least Liberty first, then to Ocata or later.

.. releasenotes/notes/default-apiv1-disabled-9f6bb0c67b38e670.yaml @ b'7fcca079ff63f1a1b6d4d3067508883f01515add'

.. releasenotes/notes/operate-migrated-groups-with-cp-apis-e5835c6673191805.yaml @ b'44ebdd22526e9a4ae0646d9f9ae2b391e70bed57'

- After running the migration script to migrate CGs to
  generic volume groups, CG and group APIs work as follows.

  * Create CG only creates in the groups table.
  * Modify CG modifies in the CG table if the CG is in the
    CG table, otherwise it modifies in the groups table.
  * Delete CG deletes from the CG or the groups table
    depending on where the CG is.
  * List CG checks both CG and groups tables.
  * List CG Snapshots checks both the CG and the groups
    tables.
  * Show CG checks both tables.
  * Show CG Snapshot checks both tables.
  * Create CG Snapshot creates either in the CG or the groups
    table depending on where the CG is.
  * Create CG from Source creates in either the CG or the
    groups table depending on the source.
  * Create Volume adds the volume either to the CG or the
    group.
  * default_cgsnapshot_type is reserved for migrating CGs.
  * Group APIs will only write/read in/from the groups table.
  * Group APIs will not work on groups with default_cgsnapshot_type.
  * Groups with default_cgsnapshot_type can only be operated by
    CG APIs.
  * After CG tables are removed, we will allow default_cgsnapshot_type
    to be used by group APIs.
