20.3.1
^^^^^^

Bug Fixes

* Bug #1980268 (https://bugs.launchpad.net/cinder/+bug/1980268):
  When creating a volume from an image, a check has been added to
  compare the requested volume size to the image's "virtual_size"
  property and fail the request if the volume will be too small to
  contain the image. If the image record does not contain this
  property, the request is accepted but the volume will go to "error"
  status if the image does not fit (which is the current behavior).

* Infinidat Driver bug #1981982
  (https://bugs.launchpad.net/cinder/+bug/1981982): Fixed Infinidat
  driver to use TLS/SSL communication between the Cinder volume
  service and the storage backend. Admin can set *True* or *False* for
  the *driver_use_ssl* and *suppress_requests_ssl_warnings* options in
  the driver section of cinder.conf to enable or disable these
  features.

* Bug #2008017 (https://bugs.launchpad.net/cinder/+bug/2008017):
  Fixed NetApp NFS driver to never spawn a native thread avoid thread
  starvation and other related issues.

* Bug #1945500 (https://bugs.launchpad.net/cinder/+bug/1945500): The
  original attempt at fixing this bug did not account for differences
  in how glance and cinder store image metadata, and as a result some
  image properties were not filtered out. This new improved fix
  addresses those differences and makes the filtering more thorough.

* PowerFlex driver bug #1942095
  (https://bugs.launchpad.net/cinder/+bug/1942095): Fixed Cinder
  volume caching mechanism for the driver. Now the driver correctly
  raises "exception.SnapshotLimitReached" when maximum snapshots are
  created for a given volume and a volume cache is invalidated to
  allow a new row of fast volume clones.

* RBD driver bug #1960206
  (https://bugs.launchpad.net/cinder/+bug/1960206): Fixed
  "total_capacity" reported by the driver to the scheduler on Ceph
  clusters that have renamed the "bytes_used" field to "stored".
  (e.g., Nautilus (https://docs.ceph.com/en/nautilus/releases/nautilus
  /#upgrade-compatibility-notes)).
