Hi Vanay, Thanks for the suggestion. I've used "qemu-img convert" before to manually migrate the other direction VMDK -> RAW/COW2. It's a great tool.
Specifically, I'm curious if the volume migration process can be managed by Cinder. For instance, we currently have 2 Cinder backends in production, NetApp NFS and HPE 3Par FC. A Cinder type is associated with each Cinder backends, you can then migrate a cinder volume between these via the command "cinder retype <volume-id> <volume-type> --migration-policy on-demand". In this case, the Cinder-volume service converts the volume from a .RAW file on a NFS filesystem, to a Fibre Chanel LUN on the 3par or visa-versa. If I had a VMDK backend in Cinder setup as another Cinder volume type, can you use Cinder to change the volumes backend and migrate the volume? For instance, can I do a "cinder retype/migrate <volume-id>" to convert the volume from a .RAW on a NetApp backend to a .vmdk on VMDK backend? The Cinder documentation is quite unclear about this. > You should be able to do this. I've done this many times using the qemu-img > tool and using the covert option.
