I think this patch is need to make sure that we don't create VDI when
the copies aren't promised.

Speaking of 'this area', did you mean 'different VDI redundant level'
feature? If so, it is very nice of you to have this feature
implemented. But I think that should be a different patch set, if you
are fine with this patch, I'm going to merge it.

Thanks,
