It can be used to enlarge or shrink an unmounted file system located on device. If the filesystem is mounted, it can be used to expand the size of the mounted filesystem, assuming the kernel supports on-line resizing..." If I understand correctly, you can only extend ext3-partition with it. But shrinking must be done off-line, on unmounted fs... Concerning resizing, I was wrong with blaming lvm2 for not being able to resize fs online. It is really problem of filesystem which might (or not) support it. I'm using ext3 because it is one of two linux-supported fs I have some experience with (the other is reiserfs, and I have some serious doubts about its future)...
