I have NOT reproduced this issue on 
ENVIRONMENT:
HA mode, CentOS, Neutron with GRE segmentation, Cinder LVM, 1 controller, 1 (compute + cinder)

I also have NOT reproduced this issue on
ENVIRONMENT:
HA mode, CentOS, Neutron with GRE segmentation, Ceph RBD for images, volumes, Ceph RadosGW for objects, 1 controller, 1 (compute + ceph)

But I have reproduced this issue on
ENVIRONMENT:
HA mode, CentOS, Neutron with GRE segmentation, Ceph RBD for images, volumes, EPHEMERAL VOLUMES, Ceph RadosGW for objects, 1 controller, 1 (compute + ceph)

It looks like the problem is related to using Ceph RBD for ephemeral volumes. In compute.log I have seen the following error:
