Cinder create volume from image bug

Openstack cascade current is developed based on Icehouse version. While in Icehouse version there is a bug about creating volume from image and uploading volume to image. Please referer to the http links https://bugs.launchpad.net/cinder/+bug/1308058 for details. This bug is recommended to fix in cascaded cinder.

Key modules

  • when create volume from image or upload volume to image, cinder will call a function in glance.py to check image metadata, while not all the metadata will be included from glance image information. As a result, in the function _extract_attributes included in file,not all the element such as "cheksum" will be validated :

    cinder/image/glance.py

Requirements

  • openstack icehouse has been installed

We suggest a way to fix the cinder-image-metadata bug. In this section, we will guide you through fix this image metadata bug.

  • Manual Installation as the OpenStack Community suggest
