Solution Verified - Updated -

Environment

Red Hat OpenStack Platform 13.0

Issue

  • Horizon GUI Unable to Retrieve instance list after performing FFU of RHOSP10 environment.

  • After updating to RHOSP13, we get the following error in log horizon logs:

    WARNING horizon.exceptions Recoverable error: This service is older (v15) than the minimum (v30) version of the rest of the deployment. Unable to continue. (HTTP 400) (Request-ID: req-669c408d-2487-4622-8179-cb9930716034)

Resolution

Please create a case for Red Hat technical support: DB surgery is likely needed and it should be performed by Red Hat's associates.

Root Cause

  • The error occurs when we have db entries for both versions 15 and 30 for nova service.
  • The issue was tracked in the BZ and fixed in the version openstack-nova-17.0.10-10.el7ost of RHOSP13.

Diagnostic Steps

  • Verify in nova DB the version of services.

    MariaDB [nova]> select id, host, version, uuid, created_at, updated_at from services ;
