18.1.0
^^^^^^


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

* The "nova-manage db online_data_migrations" command now returns
  exit status 2 in the case where some migrations failed (raised
  exceptions) and no others were completed successfully from the last
  batch attempted. This should be considered a fatal condition that
  requires intervention. Exit status 1 will be returned in the case
  where the "--max-count" option was used and some migrations failed
  but others succeeded (updated at least one row), because more work
  may remain for the non-failing migrations, and their completion may
  be a dependency for the failing ones. The command should be
  reiterated while it returns exit status 1, and considered completed
  successfully only when it returns exit status 0.


Bug Fixes
*********

* The "long_rpc_timeout" configuration option is now used for the
  RPC call to the scheduler to select a host. This is in order to
  avoid a timeout when scheduling multiple servers in a single request
  and/or when the scheduler needs to process a large number of hosts.

* A new
  "[workarounds]/report_ironic_standard_resource_class_inventory"
  configuration option has been added.

  Starting in the 16.0.0 Pike release, ironic nodes can be scheduled
  using custom resource classes rather than the standard resource
  classes VCPU, MEMORY_MB and DISK_GB:

  https://docs.openstack.org/ironic/rocky/install/configure-nova-
  flavors.html

  However, existing ironic instances require a data migration which
  can be achieved either by restarting "nova-compute" services
  managing ironic nodes or running "nova-manage db
  ironic_flavor_migration". The completion of the data migration can
  be checked by running the "nova-status upgrade check" command and
  checking the "Ironic Flavor Migration" result.

  Once all data migrations are complete, you can set this option to
  False to stop reporting VCPU, MEMORY_MB and DISK_GB resource class
  inventory to the Placement service so that scheduling will only rely
  on the custom resource class for each ironic node, as described in
  the document above.

  Note that this option does not apply starting in the 19.0.0 Stein
  release since the ironic compute driver no longer reports standard
  resource class inventory regardless of configuration.

  Alternatives to this workaround would be unsetting "memory_mb"
  and/or "vcpus" properties from ironic nodes, or using host
  aggregates to segregate VM from BM compute hosts and restrict
  flavors to those aggregates, but those alternatives might not be
  feasible at large scale.

  See related bug https://bugs.launchpad.net/nova/+bug/1796920 for
  more details.

* When testing whether direct IO is possible on the backing storage
  for an instance, Nova now uses a block size of 4096 bytes instead of
  512 bytes, avoiding issues when the underlying block device has
  sectors larger than 512 bytes. See bug
  https://launchpad.net/bugs/1801702 for details.

* The "os-simple-tenant-usage" pagination has been fixed. In some
  cases, nova usage-list would have returned incorrect results because
  of this. See bug https://launchpad.net/bugs/1796689 for details.
