Description zhouweigang09 2017-08-11 09:07:21 UTC 
Description of problem:

Change Huawei driver's private data storing place to fix issues below:

This patch is to fix issues at two circumstances:
1. Create volume from image by non-admin user, this operation will fail because Huawei driver tries to record LUN WWN at admin metadata, however non-admin user doesn't have the admin metadata access right, so exception is raised.

2. Restore volume backup to 3rd volume, this operation will also restore backup volume's metadata to the 3rd volume, but the data recorded in metadata is strong correlative to the corresponding LUN at backend storage, so this will break the one-to-one relationship between the restored volume and the LUN at storage.

To fix the issues above, we moved all LUN private data to provider_location, stored as a dict string, not use admin metadata or metadata to store LUN private data.

So it's necessary to backport to redhat openstack 11(Ocata) stable branch for Huawei cinder driver.



Version-Release number of selected component (if applicable):
Redhat Openstack 11, python-cinder

How reproducible:

Steps to Reproduce:
1. login as no-admin user
2. excute create a volume from image task
3. create task failed

Actual results:
create task fails due to admin metadata access Permission denied。


Expected results:
Create a volume from image from non-admin user successfully.
