(Get the code!)
Apologies if I wasn't clear enough.
The disconnect call I say it's probably being ignored/swallowed is the one to os-brick, not Cinder. In other words, Nova first calls os-brick to disconnect the volume from the compute host and then always considers this as successful (at least in some scenarios, probably instance destruction). Since it always considers in those scenarios that local disconnect was successful it calls Cinder to unmap/unexport the volume.
The force=True parameter to os-brick's disconnect_volume should only be added when the BDM for the volume has the delete on disconnect flag thingy.
OS-Brick has the information, the problem is that multipathd is the one that is adding the leftover devices that have been reused to the multipath device mapper.
