Additional comments:

ReiserFS 3 can be enlarged while mounted, but shrunk only when unmounted.

ReiserFS 4 can not yet be resized at all.

EXT2/3 can be enlarged online with a kernel patch and utils from
http://ext2resize.sourceforge.net/

XFS must be mounted while enlarging but can AFAIK not be shrunk, even 
off-line.

JFS must be mounted while enlarging but can not be shrunk, same as XFS.
