Do we have a patched to cinder ?
Comment 1 Alan Bishop 2018-09-04 12:18:35 UTC 
I looked over the customer case, and from what I can tell they do not have cinder's image volume cache enabled. From the information available, I think the customer is hitting bug #1555188. The fix eliminates the synchronization lock entirely when the cache is disabled.
