Using mount --bind to save space on partition

Hi all, I have created a bind mount to move data to a larger partition. Mount is showing this /usr/local/stuff on /home/stuff type none (rw,bind)
Once mounted I copy some files into /usr/local/stuff, but when I run command 'df' it's now showing less free space then I had before? Any ideas? Thanks

  Hello :) You can try recalculating disk space usage with the following command: /scripts/fixquotas
  Thank you.

  Hi Michael, I didn't think quotas applied to system directories eg /usr ?

  You can paste the output from the following commands: mount cat /etc/fstab
  Thank you.

  Hi Michael, I've worked out the issue, in /etc/fstab I had the directories around the wrong way. I've changed it to this /home/stuff /usr/local/stuff none bind 0 0
  When I then 'mount /home/stuff' is doesn't occupy any space in /usr, which is what I was expecting to see. Thanks for your help!
