You can't. You don't want to. The time you have spent waiting for a reply, you could have more productively spent waiting for the resync to complete. It probably would have completed by now. (Well, actually you can by changing about 1 line in mdadm and re-creating the array, but I'm not going to tell you which line because I really don't think you want to do it. I think mkraid has an option that lets you do this, and I don't recommend mkraid, and if you figure out how to do it, and do it, and you loose you data, then just remember that I told you that you didn't want to, and I apologise for telling you about mkraid...)
