[plug] convert existing setup to raid without data loss

[Bill Kenworthy]

I have two 60g HD's on a kt7a-raid board running Mandrake (reiserfs) and
want to experiment with software raid (raid 0 to get max write speed for
video work).  As there is already about 40G of data on the machine (much
could be deleted though - old whole OS backups for instance!)

Is it possible to convert these to raid without data loss, either in
whole or part?  It seems I can shrink the existing partions using the
reiserfstools/cfdisk and create more as raid, but once the data is
transferred, the docs get a bit vague about whether the raid partitions
can be moved and expanded to reclaim the remaining space.
