Description Sergey Gotliv 2016-02-18 08:32:07 UTC

Description of problem:

Cinder retype command fails if volume doesn't have a source type.

Version-Release number of selected component (if applicable):

We discovered it in OSP 5.0 but it seems that this issue can 
happen even in the master branch.

How reproducible:
100% on OSP 5.0


Steps to Reproduce:
1. Make sure that cinder.conf doesn't specify a default volume type
2. Create volume without specifying volume type
3. Retype this volume to the new type

Actual results:

Retype fails

Expected results:

Volume should get retyped

Additional info:

1. Configuring a default volume type in cinder.conf resolves that issue.
2. Use cinder migrate instead of retype if all you want is to move volume between different backends.

The patch is merged for Mitaka upstream.
