This occurs with the Quobyte driver but the code run is almost exclusively from the remotefs driver classes, which is why is think this will be hit by most remotefs drivers.
It can be reproduced by running the Tempest test_volumes_backup test
tempest.
with a remotefs based driver that uses snapshots for cloning volumes.
I have got this problem too. NFS storage, Queens, openstack- cinder- 12.0.1- 1.el7.noarch
