Migrate volume between backends in an async way
If we want to migrate a available volume from one backend to another backend, the current way we can choose is host-copy, using ‘dd’ command which will take a mess of resources on the Cinder node, and with no guarantee for data integrity. Also, the ‘dd’ way make the volume not usable until the host-copy is totally completed, this will be a very long time even the volume is in a medium size.
This spec is trying to find a way to migrate volume more efficient and reliable between different backends, and make the volume usable immediately after issued migration task.
