12.0.2
^^^^^^


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

* 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.

* Cinder-manage DB sync command can now bump the RPC and Objects
  versions of the services to avoid a second restart when doing
  offline upgrades.

* Dell EMC Unity Cinder driver allows enabling/disabling the SSL
  verification. Admin can set *True* or *False* for
  *driver_ssl_cert_verify* to enable or disable this function,
  alternatively set the *driver_ssl_cert_path=<PATH>* for customized
  CA path. Both above 2 options should go under the driver section.


Known Issues
************

* 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.


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

* 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*


Bug Fixes
*********

* NetApp ONTAP NFS (bug 1690954): Fix wrong usage of export path as
  volume name when deleting volumes and snapshots.

* Dell EMC Unity Driver: Fixes bug 1759175 to detach the lun
  correctly when auto zone was enabled and the lun was the last one
  attached to the host.

* 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.

* After an offline upgrade we had to restart all Cinder services
  twice, now with the *cinder-manage db sync --bump-versions* command
  we can avoid the second restart.


Other Notes
***********

* Dell EMC VNX driver: Enhances the performance of create/delete
  volume.
