AssertionError: Failed 1 OSTF tests; should fail 0 tests. Names of failed tests:
  - Create volume and attach it to instance (failure) Time limit exceeded while waiting for volume becoming 'available' to finish. Please refer to OpenStack logs for more details.

Don't see anything bad in cinder volume logs, so that probably some temp issue, but I guess that needs additional attention.
