Well that is surely a rather incomplete question, since you do not even mention which raid level you're talking about. That said, I don't think this is possible, in most cases. Raid 5 cannot use a disk which is smaller than its peers AFAIK, and neither can raid 1. Obviously too, since they cannot be expected to just 'throw away' part of their data... Whether raid 0 and/or JBOD can I don't know; sure they can be _built_ with all sorts of differing drive sizes, but I seem to recall those levels are not supported by any on- or offline resizing tool (and they are by definition not fault-tolerant so the issue of _replacing_ a drive is thereby moot...). If you're looking for trouble / complexity you could consider to make a raid 0 array out of two smaller drives, and add that combo to your existing raid set. Don't know if raid 5 will accept that, but raid 1 will. But such solutions will probably not contribute to stability and reliability...
