Best way to copy /usr to different partition?

I was getting dangerously close to running out of disk space
since /usr was filling up fast.
I thought it was simple to tar-copy /usr to a different drive/partiton
using tar copy such as:
(cd /usr; tar cpf - .) | (cd /newpartition; tar xpf -)
I tar copied the contents of /usr into my new drive/partition
and I changed the partition label to /usr, updated my
/etc/fstab file, renamed my /usr to /usr-b, created
an empty directory /usr, chmod it to 775, mounted
/usr - and it all looked fine. I then unmounted /usr,
and then rebooted.
The reboot reported that there was a problem with
the two library files: somelibfile.so.1 and somelibfile.so.2
and then gnome came up with user/password screen.
I logged in as a normal user, and after that point, I a
black screen came up with the gnome-X-cursor and
then stopped. Nothing worked at this point.
I then rebooted using rescue CD, and examined the
messages log file and it appears that selinux reported
all sorts of AVC denied over /usr and other non-system
mounted filesystems.
Clearly, it seems that selinux is having problems.
I suppose I can reboot setting the selinux = 0 and then
begin the task of somehow repairing selinux tags in all
of my files? Does this make any sense?
Anyone have a better solution?
I could reverse the /usr process and get rename /usr-b
and comment out the /usr from my fstab, but I wanted
some input from member in this forum before attempting
to do that - I would end up back to my original disk-space
problem.
Any advice?
