Overcloud deployment with Contrail missing neutron quota_driver configuration

Solution Verified - Updated -

Issue

  • After running Overcloud deploy on an existing RHOSP 16.2 environment, OpenStack is unable to retrieve quota information upon logging into the Horizon dashboard. On the other hand, such an issue does not occur in the newly created RHOSP 16.2.
  • In the existing environment, the RHEL package is manually updated/upgraded after the Overcloud deployment has been completed.
  • The following quota_driver definitions will be removed from neutron.conf after the existing Overcloud deploy is performed.
quota_driver = neutron_plugin_contrail.plugins.opencontrail.quota.driver.QuotaDriver

Environment

  • Red Hat OpenStack Platform 16.2
  • Neutron Contrail 21.4 plugin
