Cannot create a volume from an image after the image's properties were edited

[Yogev Rabl]

Description of problem:
The creation of a volume from an image failed after the minimum RAM, minimum disk and shared properties have been edited.
Cinder was able to create a volume from images that their properties were not edited (and were different than 0)

Version-Release number of selected component (if applicable):
python-cinder-2015.1.0-2.el7ost.noarch
python-cinderclient-1.1.1-1.el7ost.noarch
openstack-cinder-2015.1.0-2.el7ost.noarch
openstack-glance-2015.1.0-6.el7ost.noarch

How reproducible:
100%

Steps to Reproduce:
1. Create an image
2. Edit the image properties (min. RAM/Disk or shared/protected)
3. Create a volume from the image

Actual results:
In the Horizon the error message is: Error: Unable to create volume.
In the CLI the error is:
ERROR: Internal Server Error (HTTP 500) (Request-ID: req-1afecc0d-2647-4387-83cc-11ba214b2cad)

Expected results:
A new volume can be created from any image

Can't reproduce on upstream

Which OS are you using?

[Lisa Li (lisali)]

I also can't recreate the bug.
Please add the detailed command you run.
And plus cinder-api, cinder-volume and cinder-scheduler logs better.

[Yogev Rabl (yrabl)]

Lisa, can you please add the versions of the packages of Glance/Cinder that you are currently using?

[Lisa Li (lisali)]

I use devstack to install my environment.
$ cinder --version
1.2.1
cinder-manage --version
2015.2.0
$ glance --version
0.18.0
$ glance-manage --version
2015.2.0

I have just taken a look at this issue, and tried to reproduce it in devstack. Just like Lisa, I could not witness the bug.

1) I used the "cirros-0.3.4-x86_64-uec" image provided by devstack.

2) I edited it by running:

$ glance image-update d164e9b7-aaed-4717-b21c-b2ccf4beb80e --min-ram 128 --min-disk 1 --protected True

And checked that the image had been correctly updated using "glance image-show"

3) I created a volume from this image by running:

$ cinder create 1 --display-name test2 --image-id cirros-0.3.4-x86_64-uec --availability-zone nova

It worked perfectly, and the volume appears as "available" in the list returned by "cinder list".

Hi ,

I was unable to reproduce the bug with the below versions too. I even tried updating the glance image multiple times...but the issue was not reproducible

My service versions:

ubuntu@karthikvm:~/devstack$ cinder --version
1.6.0
ubuntu@karthikvm:~/devstack$ cinder-manage --version
8.0.0
ubuntu@karthikvm:~/devstack$ glance-manage --version
12.0.0
