Fixed In Version: openstack-cinder-12.0.4-4.el7ost
Doc Type: Bug Fix
Doc Text:
Cause: Previously, when performing image operations in Cinder, users experienced errors on RabbitMQ and DB connections because file I/O operations blocked greenthreads, preventing switching to another greenthread on I/O Consequence: As a result, the cinder-volume service was `down` when creating an image from a volume. Fix: With this update, image operations that can prevent greenthread switching are executed in native threads. Result: As a result, the cinder-volume service no longer appears `down` to the scheduler.

Verified on:
openstack-cinder-12.0.4-8.el7ost.noarch

Uploaded a rhel (~500mb) image to glance. 
Created a volume from this image:
#cinder create 10 --image rhel


Upload volume to a new image:
openstack image create --volume f04101e9-2c07-46f3-84bb-9a33dc1f809a imageFromVol 

While doing this I watched -d -n 2 openstack volume service list

Cinder volume remains up the whole time, 
tried a few time same "up" status remains, never it go down. 

Image is available:
