If /dev/hda6 is necessary to keep ubuntuserver running, you won't be able to umount.

If you have a file open from /dev/hda6, you won't be able to umount.

If you have a file manager running and open to a file/directory on /dev/hda6, you won't be able to umount.

You would probably have to shutdown, and boot from a liveCD to resize /dev/hda6.
