It sounds like you were trying to use Parted to resize a partition containing
a file system that was still mounted.  In other words, you tried to resize a
partition that Linux (the kernel) was allowed to write to.  As you'd expect,
that's not a good idea.

So you must first unmount the file system on that device using a command like:

        # umount /usr

But since /usr is such an important and frequently used part of the system, I
think you'll actually be better off running Parted from a boot disk (in fact,
you might not really have a choice).  That way you can run Parted on the machine
with none of the file systems on your server's disks being mounted at the time.

See the Parted manual http://www.gnu.org/manual/parted-1.6.1/ for more
information.  Actually, from memory, I think the section on creating a boot disk
is out of date and that you need to create two disks, a root disk and a boot
disk.  There is more information to be found at the FTP site mentioned in that
