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

* This release contains a fix for Bug #1908315
  (https://bugs.launchpad.net/cinder/+bug/1908315), which changes the
  default value of the policy governing the Block Storage API action
  Reset group snapshot status (https://docs.openstack.org/api-ref
  /block-storage/v3/#reset-group-snapshot-status) to make the action
  administrator-only.  This policy was inadvertently changed to be
  admin-or-owner during the Queens development cycle.

  The policy is named "group:reset_group_snapshot_status".

  * If you have a custom value for this policy in your cinder policy
    configuration file, this change to the default value will not
    affect you.

  * If you have been aware of this regression and like the current
    (incorrect) behavior, you may add the following line to your
    cinder policy configuration file to restore that behavior:

       "group:reset_group_snapshot_status": "rule:admin_or_owner"

    This setting is *not recommended* by the Cinder project team, as
    it may allow end users to put a group snapshot into an invalid
    status with indeterminate consequences.

  For more information about the cinder policy configuration file, see
  the policy.yaml
  (https://docs.openstack.org/cinder/latest/configuration/block-
  storage/samples/policy.yaml.html) section of the Cinder
  Configuration Guide.

* The default value of the configuration option,
  "glance_num_retries", has been changed to 3 in this release. Its
  former value was 0. The option controls how many times to retry a
  Glance API call in response to a HTTP connection failure, timeout or
  ServiceUnavailable status. By this change, Cinder can be more
  resilient to temporary failure and continue the request if a retry
  succeeds.


Bug Fixes
*********

* Bug #1888951 (https://bugs.launchpad.net/cinder/+bug/1888951):
  Fixed an issue with creating a backup from snapshot with NFS volume
  driver.

* RBD driver bug #1901241
  (https://bugs.launchpad.net/cinder/+bug/1901241): Fixed an issue
  where decreasing the "rbd_max_clone_depth" configuration option
  would prevent volumes that had already exceeded that depth from
  being cloned.

* Bug #1908315 (https://bugs.launchpad.net/cinder/+bug/1908315):
  Corrected the default checkstring for the
  "group:reset_group_snapshot_status" policy to make it admin-only.
  This policy governs the Block Storage API action Reset group
  snapshot status (https://docs.openstack.org/api-ref/block-storage/v3
  /#reset-group-snapshot-status), which by default is supposed to be
  an adminstrator-only action.

* Bug #1883490 (https://bugs.launchpad.net/cinder/+bug/1883490):
  Fixed incorrect response of listing volumes with filters.

* Bug #1863806 (https://bugs.launchpad.net/cinder/+bug/1863806):
  "os- reset_status" notifications for volumes, snapshots, and backups
  were being sent to nonstandard publisher_ids relative to other
  cinder notifications for volumes, snapshots, and backups. Now they
  are also sent to the following *standard* publisher_ids, where most
  people would expect to find them:

  * 'volume' for volume status resets

  * 'snapshot' for snapshot status resets

  * 'backup' for backup status resets

* Bug #1898587 (https://bugs.launchpad.net/cinder/+bug/1898587):
  Address cloning and api request timeout issues users may hit in
  certain environments, by allowing configuring timeout values for
  these operations through cinder configuration file.

* NetApp SolidFire driver Bug #1896112
  (https://bugs.launchpad.net/cinder/+bug/1896112): Fixes an issue
  that may duplicate volumes during creation, in case the SolidFire
  backend successfully processes a request and creates the volume, but
  fails to deliver the result back to the driver (the response is
  lost). When this scenario occurs, the SolidFire driver will retry
  the operation, which previously resulted in the creation of a
  duplicate volume. This fix adds the "sf_volume_create_timeout"
  configuration option (default value: 60 seconds) which specifies an
  additional length of time that the driver will wait for the volume
  to become active on the backend before raising an exception.

* NetApp SolidFire driver Bug #1891914
  (https://bugs.launchpad.net/cinder/+bug/1891914): Fix an error that
  might occur on cluster workload rebalancing or system upgrade, when
  an operation is made to a volume at the same time its connection is
  being moved to a secondary node.
