Description shilpa 2015-07-11 17:25:15 UTC

Description of problem:
Using ceph as backend, uploaded a glance image using the taskflow option. The image is converted and uploaded successfully. However the glance task-create command ends with a response "HTTPInternalServerError" with traceback errors in the logs 

Version-Release number of selected component (if applicable):
openstack-glance-2015.1.0-6.el7ost.noarch
python-glance-store-0.4.0-1.el7ost.noarch
python-glance-2015.1.0-6.el7ost.noarch
python-glanceclient-0.17.0-2.el7ost.noarch

ceph version: ceph-0.94.1-13.el7cp.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Configure glance to use rbd. 
2. Configure taskflow option.
[task]
task_executor = taskflow
work_dir=/tmp

[taskflow_executor]
engine_mode = serial
max_workers = 10
conversion_format=raw

3.Upload a local image to glance stored on controller node using task-create command.
#glance --os-image-api-version 2 task-create --type import --input '{"import_from_format": "qcow2", "import_^Com": "http://127.0.0.1:8000/cirros-0.3.0-x86_64-disk.img","image_properties": {"name": "CirrOS-test1", "disk_format": "qcow2", "container_format": "bare"}}'

Used the controller node as a simple HTTP server to fetch a qcow2 image from.

4.Glance image is converted to raw and uploaded successfully.

# glance image-list
| b5a8ab54-087e-46f5-ae27-8a960dd4eef9 | CirrOS-test1  | raw         | bare             | 41126400    | active |

5. On ceph image pool the glance image is created successfully.

"rbd info images/b5a8ab54-087e-46f5-ae27-8a960dd4eef9"
root.27.33's password:

	order 23 (8192 kB objects)
	block_name_prefix: rbd_data.37de7042fba6
	format: 2
	features: layering
	flags: 


Actual results:
The response status is HTTPInternalServerError with errors in api.log file. 

Expected results:
A valid response status.

I'll report this upstream

Comment 4 shilpa 2015-10-20 11:05:12 UTC

Ran this test again with OSP 7 with ceph 1.3.1 with following packages:
openstack-glance-2015.1.1-1.el7ost.noarch
python-glance-2015.1.1-1.el7ost.noarch
python-glanceclient-0.17.0-2.el7ost.noarch

Now the issue is that the image fails to get created on rbd. It just stays queued.

api.conf:

[task]
task_executor = taskflow
work_dir = /tmp


[taskflow_executor]
engine_mode = serial
max_workers = 10
conversion_format = raw
