Hi all,

https://bugs.launchpad.net/cinder/+bug/1255622
For this bug, I have added some comments to explain why the "orphaned 
volume" that ends up in the end of the migration.
@John Griffith, I hope this can resolve your confusion a bit.

Best wishes,
Vincent Hou (侯胜博)

All,

In discussion with Mike Perez earlier this week the following bugs were 
highlighted in Volume Migration and Volume Replication.  IBM is focusing 
on investigating and resolving these bugs.

I will be putting out updates as we progress towards resolution of these 
issues.

https://bugs.launchpad.net/cinder/+bug/1308315.-- Tao is investigating but 
hasn't been able to recreate.

While triaging all the issues I updated the ones for migration with a 
'migration' tag and updated the replication ones with a 'replication' tag.

If you have any questions/concerns about this, please let me know.  
Otherwise we will work towards cleaning these up.

Thanks!
Jay
