This should work with the filesystem mounted. Having said that, I've only ever used it on ext3 (journalling), but the man page says it's ext2 so you should be fine. The filesystem should be extended after that. As it stands at the moment you've just extended the nr of extents available but not yet used them. Some shops do that to make it easy to extend filesystems when they fill up. Good luck, Nick .
