14.2.4
^^^^^^


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

* Removed dependency for "cinder_backends_rbd_inuse" in nova.conf
  when setting "rbd_user" and "rbd_secret_uuid" variables. Cinder
  delivers all necessary values via RPC when attaching the volume, so
  those variables are only necessary for ephemeral disks stored in
  Ceph. These variables are required to be set up on cinder-volume
  side under backend section.

* New variables have been added to allow a deployer to customize a
  nova systemd unit file to their liking.

* The task dropping the nova systemd unit files now uses the
  "config_template" action plugin allowing deployers access to
  customize the unit files as they see fit without having to load
  extra options into the defaults and polute the generic systemd unit
  file with jinja2 variables and conditionals.

* For the "os_nova" role, the systemd unit "TimeoutSec" value which
  controls the time between sending a SIGTERM signal and a SIGKILL
  signal when stopping or restarting the service has been reduced from
  300 seconds to 120 seconds. This provides 2 minutes for long-lived
  sessions to drain while preventing new ones from starting before a
  restart or a stop. The "RestartSec" value which controls the time
  between the service stop and start when restarting has been reduced
  from 150 seconds to 2 seconds to make the restart happen faster.
  These values can be adjusted by using the
  "nova_*_init_config_overrides" variables which use the
  "config_template" task to change template defaults.
