this looks like a tempest failure and if not tempest its a cinder error.

[Mike Perez (thingee)]

Since Havana, if you create a volume in cinder that has a specified volume type, it will introduce new default quotas. Seeing that these tests were introduced in tempest 2014-02-20, I'm guessing some race condition is hit where if these tests are ran before volume creation tests, you would pass.

    fix cinder quota equality

    The cinder quota test was of bad quality, and assumed that all
    the functions in the class ran in linear order to work. If they
    run in a different order the tenant could have additional quota
    values beyond the strict defaults.

    We can fix this by testing the returned quota contains the values
    we're attempting to update.
