Did you try it with a "-v" option to see what it was doing?  Did you
check /var/log/messages and the output of "dmesg" to see if any errors
were spewed out?

You mean when you remount /data it still shows as a 2GB filesystem?
How big is /dev/hda8?

It should have, unless /dev/hda8 isn't 4G in size.  If there's an
issue, I'd expect an error message...either on the console or in
/var/log/messages or dmesg.
