okay, i'll rephrase.... being an old aix hand... with the (possible)  
exeption of reiser.... I, personally, would not trust any filesystem  
to resize without being unmounted.  but then, compared to the aix  
lvm, which can be resized with oracle accessing at full speed, linux  
lvms are just barely getting to what I'd call "production ready".   
interesting to see that we're moving in an online-resizable direction  
on linux. :)
