ALWAYS fsck after growfs.

growfs is crappy at least, zero out the new space before growfs, but just 
if you can - simply backup data somewhere and use newfs.

growfs is for people that like challenges ;)

i have to use it growing 800GB filesystem to 1400GB, finally (after 
patching it a bit) i did it, but root directory was destroyed (no idea 
why). all subdirs appeared in lost+found so it wasn't a big problem 
then+i've got zero sized file in lost+found that i was unable to delete 
until i took off all strange flash with chflags.

but i did it ONLY because i had no way to back it up.
