To make sure that we have no misunderstanding between us, did you configured the filter
not only in storage node (or probably controller node if you don't have dedicated nodes
for cinder-volume) BUT ALSO in all compute nodes ?

I'm asking this because the current documentation is not specific about this requirement
but the filter should be configured in all nodes which may attach instance volumes.

So you mean you don't see any lvms from guest instances when you do lvs/vgs/pvs in your
compute nodes ?
