This isn't a nova error as far as I can tell, it's some problem reading
from the database:

2018-05-09 16:29:33.278 11031 ERROR nova.api.openstack.extensions
DBError: (pymysql.err.InternalError) (1, u"Can't create/write to file
'/tmp/#sql_4038_1.MAI' (Errcode: 2)")

So you probably need to double check your database configuration.

Bug description:
  Description
  ===========

  Hello,

  I've got an issue regarding undercloud when I execute the command "
  Openstack server list".

  Environment
  ===========
  I'm working in Red Hat openstack Plateform 11 environment

  Steps to reproduce
  ==================
  I did "openstack server list" but it's returned me this : 

  "Erreur de l'API inattendue. Merci de la reporter sur http://bugs.launchpad.net/nova/ et d'y joindre le rapport de L'API Nova si possible.
  <class 'oslo_db.exception.DBError'> (HTTP 500) (Request-ID: req-444677f3-9944-4522-a67c-865cea7d33b4)"

  Then i Did the same command with "--debug" and here the result :

  I don't know where the issue could be at. If someone has an idea, I'll
  be pleased to take it.
