Comment 2 for bug 1752115

The disconnect is happening in a nova-cpu call to os-brick. The path is:

block_device.driver_detach >
libvirt.driver.detach_volume >
libvirt.driver._disconnect_volume >
os_brick.vol_driver.disconnect_volume

which disconnects the volume.

the os-brick version is 2.3.0.

nova version:
