Follow these steps and it should work very well.  If nervous about 
following these steps, follow the steps for /home first and after it 
works and you are comfortable then repeat the steps to do /var.
Use tar because it easily maintains ownership and permissions whereas cp 
requires special flags to do that.
This all must be done as root.

1.  create 2 mount points in /mnt.
        call them /mnt/home and /mnt/var

2. mount the appropriate partition on each.
        mount /dev/hdb1 /mnt/home   etc.

3. create tar files (This assumes you have at least twice the currently 
used space in each of the new partitons.  If not, choose a different 
location where space is available to create the tar files, or do just 
one filesystem at a time and use the other partition as the location to 
create that file.)
        #  tar cvf /mnt/home/home.tar /home
        #  tar cvf /mnt/var/var.tar  /var

4. Now extract the tarball to the new partitions
        #  cd /mnt
        #  tar xvf home/home.tar
        #  tar xvf var/var.tar
5.  do a quick verification of the completeness of both new sets of 
files extracted.
    A quick way to check it is close is
        du -s /var
        du -s /mnt/var
    The numbers should be very close if not exact.

6. (this one can be done now or later)
        If step 5 appears good then do # rm /mnt/home.tar /mnt/var/var.tar

7. Now comes the hard (easy??) part -- actually putting the new 
filesystems on the mount point.
    a.    Edit /etc/fstab to make sure the new partitons will be mounted 
on /home and /var
    eg.    /dev/hdb1     /home   ext3    defaults        1 2
            /dev/hdb2     /var       ext3    defaults        1 2
    b.   You must remove the old contents of /home and /var _before_ you 
mount the new partions at that point so you have that space available. 
(If you do not, the space will not be available and the clearing cannot 
be done with the filesystem mounted at that point)
        (carefull on the spelling with this one)
        #  rm -rf /home/*
then
        #  rm -rf /var/*
    c:    Reboot

If you have carefully followed all the steps above, now reboot and 
everything will be on the new filesystems and space previously used will 
be free.
