{0} tempest.api.volume.admin.test_volume_quotas.BaseVolumeQuotasAdminTestJSON.test_quota_usage_after_volume_transfer [4.144642s] ... ok


Additional info:
It is possible the cinder responded on v1 before,
but according to its config it was not expected.


Changing the
   cls.alt_client = cls.os_alt.volumes_client
to
   cls.alt_client = cls.os_alt.volumes_v2_client 

helps to workaround the issue, but cls.os_alt.volumes_client expected to be a v2 client by default.
