Yes, but only for new client, not for 2.5 client. I did not check whether those legacy LMV code (<2.6) can handle this well. So I thought we better to stop the old MDT touching these striped dir to avoid trouble?

Hmm, would this already be handled by the LMV magic being different in the new layout?
