<p class="MsoNormal">Hi hemna:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">When we attach a encrypted volume and then detach it, the device path created when the volume is attached won’t be cleanup.<o:p></o:p></p>
<p class="MsoNormal">This is probably due to nova and cinder not work coordinately when detach a encrypted volume.<o:p></o:p></p>
<p class="MsoNormal">This will cause next volume attachment fails and also cause some test cases of CI fail because the not cleaned up device path.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I opened a bug in os-brick(not sure it’s a nova or os-brick bug<span style="font-family:Wingdings">J</span>):<o:p></o:p></p>

<p class="MsoNormal">And want to see if you have any idea about this?<o:p></o:p></p>
