/dev/md2       1016G  359G  606G  38% /
/dev/md1        496M   54M  418M  12% /boot
/dev/md3        1.8T  196M  1.7T   1% /data

bind mounts:
/data/home -> /home
/data/var/www -> /var/www

$ ls /data

home  var



convert it with:

mkdir /data
vim /etc/fstab # modify fstab to put md3 on /data instead of /home
umount /home
mount /data
mkdir /data/home
mkdir -p /data/var/www
vim /etc/fstab # modify fstab to put bind mounts from /data/home to /home and /data/var/www to /var/www
mount -a
