Yep, you've pretty much misunderstood the information which was being conveyed in the link I originally sent you.  You placed actual data under /nfsexports.

I would.....

unmount the exported file system from all clients.  (umount on box7 for example)

Then on the server I'd move /etc/exports to /etc/exports-orig and run "exportfs -r" and confirm by running "exportfs" that they are no longer exported.

Also on the server I'd proceed to move all the directories out of /nfsexports to /home

cd /nfsexports
mv check data Dell DigiCam Documents Download evergreene gramps home lectures /home

(Yes, you'll end up with a /home/home.   You don't really have any user home's under there to you?)

The I'd set up the directory structure under /nfsexports by doing

cd /nfsexports
mkdir -m 1777 data
mkdir -m 1777 home

Then, still on the server, I would append these lines to /etc/fstab

# bind mounts
/home/data               /nfs4exports/data   none    rw,bind 0 0
/home/home          /nfs4exports/home     none    rw,bind 0 0

Then I would

mount /nfs4exports/data
mount /nfs4exports/home

Then, when you issue the just the "mount" command you should see included....

/home/data  on  /nfs4exports/data  type none (rw,bind)
/home/home on  /nfs4exports/home  type none (rw,bind)

Or something similar....

Then I'd move /etc/exports-orig back to /etc/exports but I would change /nfs4exports back to ro.  And then do "exports -rv". 

Now..... If you just want all of the exported information to be under a single directory on box7 (client) I would do....on box7

mkdir /mnt/box8
mount 192.168.1.8:/nfsexports  /mnt/box8

And, of course, make corresponding changes in the /etc/fstab on box7
