Without the device in place, the device name is not showing up, since the missing device is not under /dev/sdXX or anything else. That is why I asked if the special parameter 'missing' may be used in a replace. I can't say if it is supported. But I guess not, since I found no documentation on this matter. So I guess replace is not aimed at fault tolerance / rebuilding. It's just a convenient way to lets lay replace the disks with larger disks , to extend your array. A convenience tool, not an emergency tool.
