Hello Manish! "openstack database instance show" command shows you the current status of an instance. If the status is not ACTIVE, guest-agent fails to start the database service for some reasons. Please see the following page for further debug.

FYI: I think the error occurs here in your case.

Best Regards,

Dear Team,

We are trying to deploy OpenStack environment for our application and while
deploying trove service we are facing the below error(attached screenshot)-

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/trove/common/", line
207, in wait_for_task
    return polling_task.wait()
  File "/usr/lib/python3/dist-packages/eventlet/", line 125, in wait
    result = hub.switch()
  File "/usr/lib/python3/dist-packages/eventlet/hubs/", line
313, in switch
    return self.greenlet.switch()
  File "/usr/lib/python3/dist-packages/oslo_service/",
line 154, in _run_loop
    idle = idle_for_func(result, self._elapsed(watch))
  File "/usr/lib/python3/dist-packages/oslo_service/",
line 349, in _idle_for
    raise LoopingCallTimeOut(
    Looping call timed out after 870.99 seconds

During handling of the above exception, another exception occurred:

    return wait_for_task(task)
  File "/usr/lib/python3/dist-packages/trove/common/", line
209, in wait_for_task
    raise exception.PollTimeOut
trove.common.exception.PollTimeOut: Polling request timed out.

Please help us on this issue.
