RHEA-2020:4400 - Product Enhancement Advisory

Topic

Updated packages that resolve various issues are now available for Red Hat
OpenStack Platform 13.0 (Queens) for RHEL 7.

Description

Red Hat OpenStack Platform provides the facilities for building, deploying
and monitoring a private or public infrastructure-as-a-service (IaaS) cloud
running on commonly available physical hardware.

Changes to the openstack-octavia component:

Before this update, the Compute (nova) service not releasing resources, such as network ports, until a Compute node is restored caused the Load-balancing service (octavia) failover to fail when it was unable to detach a network port from an instance on a Compute node that is down.

With this update, the failover flow in the Load-balancing service has been updated to work around this Compute service issue. The Load-balancing service will now abandon ports that the Compute service will not release, leaving them in a "pending delete" state for the Compute service or Networking service to clean up once the Compute node is restored. This resolves the issue, allowing failover to succeed even if the Compute node is still failed. (BZ#1723482)

Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.
