ext3 can be resized online. I think ext2resize in the latest release
will "do the right thing" whether it is online or not.

There is a limit to the amount of expansion that can be achieved
on-line.  This limit is set when making the filesystem.  Depending on
which version of ext2-utils you used to make the filesystem, it may or
may not already be prepared for substantial expansion.

So if you want to do it on-line, give it a try.... or ask on the
ext3-users list for particular details on what versions you need and
how to see if your fs can be expanded.
