I think the current code doesn't guarantee that the gateway has vdi
copy list before processing I/O requests, either.  Is it correct?

If yes, we need two fixes:

 - The gateway must notify recovery completion.
 - The gateway must have vdi copy list before processing I/Os.

To fix the first one, the gateway doesn't need to gather object list.
This is what I meant.

Thanks,
