Try this:

In Linux the command resize2fs can resize a mounted partition.

>From 'man resize2fs':
"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.)."
