Vincent,
thanks for reviewing.

Yes, that is what's happening in MD. The doc was confusing about the
"timestamp" part.

Yes, so for that case I was thinking that once the user decides to
ignore the split-brain warning and still go ahead with the assemble,
then drives that are not accessible at that point will not be used
from now on ("external entity" should take care about that). The doc
mentions that as well.
Thanks,
Alex.
