Define "safe".  You could probably do it non-destructively with dd, if 
you set the block size properly.  That doesn't make it safe, though, 
you're basically screwed if you lose power.

And even once you do that, I don't think the Reiser4 tools would let you 
resize.

Anyway, I haven't tried this myself, as my SW RAID does actually have 
multiple partitions, for good reason.
