RHBA-2020:4394 - Bug Fix Advisory

Topic

Updated OpenStack Bare Metal Provisioning packages that resolve various
issues are now available for Red Hat OpenStack Platform 13.0 (Queens) for
Red Hat Enterprise Linux (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. This advisory includes
packages for:

OpenStack Bare Metal Provisioning (ironic)

OpenStack Bare Metal Provisioning enables the user to provision physical, or bare metal machines, for a variety of hardware vendors with hardware-specific drivers. Bare Metal Provisioning integrates with the Compute service to provision the bare metal machines in the same way that virtual machines are provisioned, and provides a solution for the bare-metal-to-trusted-tenant use case.

Changes to the openstack-ironic component:

• During startup, the ironic-conductor service could lose the reservation lock on a bare metal node for work accepted early in the ironic-conductor restart process. Losing the lock caused a race condition for work submitted to an OpenStack Bare Metal Provisioning (ironic) deployment during a restart of the ironic-conductor service, which resulted in requests failing with a "NodeNotLocked" error.

With this update, the database clean-up checks are performed before work can be accepted by an ironic-conductor process, which resolves the issue. (BZ#1847305)

Changes to the openstack-ironic-python-agent component:

• Before this update, initial connection errors with the agent were disrupting the retry logic, which sometimes resulted in the agent failing to communicate with the Ironic services, and logging a misleading TypeError to the agent console.

With this update, the exception handling has been fixed to explicitly handle known possible connection and lookup failure cases, and the logging has been updated to provide clarity on what is happening with the agent. Connections are now retried as designed by the agent and logging should no longer report just a TypeError in the event of an unexpected failure. (BZ#1862105)

Solution
