Title:
  encrypted cryptsetup volume attach failure in barbican-tempest-test
  fails intermittently

Status in OpenStack Compute (nova):
  Confirmed

Bug description:
  The Barbican grenade job is failing intermittently due to a failure
  when we attempt to use an attached encrypted volume.

  The specific test being executed is here: 
  https://github.com/openstack/barbican-tempest-plugin/blob/master/barbican_tempest_plugin/tests/scenario/test_volume_encryption.py (line 161 - test_encrypted_cinder_volumes_cryptsetup)

  The failing test case occurs here:

  http://logs.openstack.org/67/628667/13/check/grenade-devstack-
  barbican/613998f

  The test that fails is: test_encrypted_cinder_volumes_cryptsetup, whereas the test 
  test_encrypted_cinder_volumes_luks  passes.

  So something is going on with cryptsetup, which fails with : 
  Could not stat /dev/vdb --- No such file or directory

  For reference,  the test http://logs.openstack.org/67/628667/13/check
  /grenade-devstack-barbican/3a71288/ succeeded, so the problem appears
  to be intermittent.
