18.1.0
^^^^^^


New Features
************

* Log a warning from the volume service when a volume driver's
  get_volume_stats() call takes a long time to return.  This can help
  deployers troubleshoot a cinder-volume service misbehaving due to a
  driver/backend performance issue.


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

* Pure Storage FlashArray minimum "purestorage" SDK version
  increased to 1.17.0


Bug Fixes
*********

* PowerFlex driver bug #1897598
  (https://bugs.launchpad.net/cinder/+bug/1897598): Fixed bug with
  PowerFlex storage-assisted volume migration when volume migration
  was performed without conversion of volume type in cases where it
  should have been converted to/from thin/thick provisioned.

* RBD driver Bug #1922408
  (https://bugs.launchpad.net/cinder/+bug/1922408): Fixed create
  encrypted volume from encrypted snapshot.

* PowerMax driver bug #1939139
  (https://bugs.launchpad.net/cinder/+bug/1939139): Fix on create
  snapshot operation that exists when using PowerMax OS 5978.711 and
  later.

* Fixed the schema validation for attachment create API to make
  instance uuid an optional field. It had mistakenly been defined as a
  required field when schema validation was added in an earlier
  release. Also updated the schema to allow specification of the
  "mode" parameter, which has been available since microversion >=
  3.54, but which was not recognized as a legitimate request field.

* NetApp ONTAP bug #1906291
  (https://bugs.launchpad.net/cinder/+bug/1906291): Fix volume losing
  its QoS policy on the backend after moving it (migrate or retype
  with migrate) to a NetApp NFS backend.

* NFS driver bug #1860913
  (https://bugs.launchpad.net/cinder/+bug/1860913): Fixed instance
  uses base image file when it is rebooted after online snapshot
  creation.

* PowerMax driver: Previously, the target storage group created from
  a replicated storage group was also replicated, which could cause
  failures. This fix creates a non-replicated target initially, and
  lets the replicate group API take care of replicating it.

* PowerMax driver: Fix to suspend the storage group you are about to
  delete and then add a force flag to delete the volume pairs within
  the storage group.

* Pure Storage FlashArray driver bug #1936663
  (https://bugs.launchpad.net/cinder/+bug/1936663): Fixes issue where
  cloning a consistency group containing volumes with very long names
  causes a crash - Required for PowerVC support

* Pure Storage FlashArray driver bug #1929219
  (https://bugs.launchpad.net/cinder/+bug/1929219): Fixes issue with
  incorrect internal mechanism for checking REST API of backend array.
  This has no external effect for users.

* Pure Storage FlashArray driver bug #1938579
  (https://bugs.launchpad.net/cinder/+bug/1938579): Fixes issue when
  cloning multiple volumes in PowerVC deployments.

* Pure Storage bug #1930748
  (https://bugs.launchpad.net/cinder/+bug/1930748): Fixed issues with
  multiattched volumes being diconnected from a backend when still
  listed as an attachment to an instance.

* Bug #1931004 (https://bugs.launchpad.net/cinder/+bug/1931004):
  Fixed use of incorrect stripe unit in RBD image clone causing
  volume-from- image to fail when using raw images backed by Ceph.

* Bug #1898075 (https://bugs.launchpad.net/cinder/+bug/1898075):
  When Glance added support for multiple cinder stores, Images API
  version 2.11 modified the format of the image location URI, which
  Cinder reads in order to try to use an optimized data path when
  creating a volume from an image.  Unfortunately, Cinder did not
  understand the new format and when Glance multiple cinder stores
  were used, Cinder could not use the optimized data path, and instead
  downloaded image data from the Image service.  Cinder now supports
  Images API version 2.11.
