:: resize2fs - ext2/ext3/ext4 file system resizer
The  resize2fs  program will resize ext2, ext3, or ext4 file systems.  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.  
(As of this writing, the Linux 2.6 kernel supports on-line resize for filesystems  mounted  using  ext3  and ext4.).
