Someone has written a patch that does this - it's not finished yet but 
it's intended to go into the 0.21 version: see 
http://svn.mythtv.org/trac/ticket/1744

However since the latest linux kernels support dynamic expansion of a 
raid5 array, I don't see much need for this for the scenarios you 
describe.See: http://scotgate.org/?p=107 and 
http://lkml.org/lkml/2006/3/20/105

If for some reason you can't upgrade to the latest kernel then there are 
ways to create an LVM on RAID that allows adding a drive to the raid 
array without needing to completely backup and start again. See 
http://ask.slashdot.org/comments.pl?sid=169386&cid=14117414

Either of these methods gives the data security of raid and the ability 
to expand storage..
