There has been a bit if mail on the reiser list about 
corruption from expanding in-use file systems. Frankly,
for the number of [milli?]seconds it takes to do the
expansion offline it seems easier to do it unmounted.

I'm also not sure that ext3 supports online extension
(thought the original post was about ext3), and ext2
or msdos file systems certianly don't.

You also don't know if anyone is using the volume for
a networked file system, which may screw things up 
if the caching is too aggressive.
