Hi hemna: When we attach a encrypted volume and then detach it, the device path created when the volume is attached won't be cleanup. This is probably due to nova and cinder not work coordinately when detach a encrypted volume. This will cause next volume attachment fails and also cause some test cases of CI fail because the not cleaned up device path. I opened a bug in os-brick(not sure it's a nova or os-brick bug:)): https://bugs.launchpad.net/os-brick/+bug/1528092 And want to see if you have any idea about this? Thanks!
