[35146] [Queens, Pike] The novav21 state fails to update aggregates

Fixed in 2019.2.10

While creating an aggregate, the novav21.aggregate_present state outputs IndexError: tuple index out of range. Although an aggregate is created, it is ignored by the Nova state and is never updated.

Identify whether your deployment is affected by the issue:

  • New deployments without aggregates are not affected.

  • New deployments with defined aggregates are affected and fail to create aggregates. No workaround is currently available for this use case.

  • Existing deployments with aggregates fail to update aggregates. The workaround is to create and update aggregates manually using Nova CLI. For details, see OpenStack documentation.
