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


I've got all this working with your help but I still have to mount the server manually. Fstab contains the following lines:

   [root@box7 bobg]# cat /etc/fstab
   #
   # /etc/fstab
   # Created by anaconda on Tue Aug  7 08:37:16 2012
   #
   # Accessible filesystems, by reference, are maintained under '/dev/disk'
   # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for

   192.168.1.8:/nfs4exports/     /mnt/BOX8     nfs4     rw,bind 0 0
   192.168.1.8:/home/   /mnt/HOME1/     nfs4    rw,bind  0 0
   192.168.1.8:/data/   /mnt/DATA1      nfs4    rw,bind  0 0
   192.168.1.48:/SRVR1              /mnt/BOX48      nfs4
   defaults,rw,user 0 0

The server box48 mounts during the boot process, box8 does not. I see the following lines in "mount":

   /dev/sdb3 on /mnt/BOX8 type ext4 (rw,relatime,seclabel,data=ordered)
   /dev/sdb3 on /mnt/HOME1 type ext4 (rw,relatime,seclabel,data=ordered)
   /dev/sdb3 on /mnt/DATA1 type ext4 (rw,relatime,seclabel,data=ordered)
   192.168.1.48://SRVR1 on /mnt/BOX48 type nfs4
   (rw,nosuid,nodev,noexec,relatime,vers=4.0,rsize=262144,wsize=262144,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=192.168.1.7,local_lock=none,addr=192.168.1.48)
   gvfs-fuse-daemon on /run/user/bobg/gvfs type fuse.gvfs-fuse-daemon
   (rw,nosuid,nodev,relatime,user_id=1000,group_id=1000)

Which raises the question why are the non-working mounts shown as /dev/sdbx while the one that mounts [box48] does not? Then after mounting manually with "[root@box7 bobg]# mount 192.168.1.8:/home/ /mnt/HOME1/" mount shows:

   192.168.1.8:/home on /mnt/HOME1 type nfs4
   (rw,relatime,vers=4.0,rsize=524288,wsize=524288,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=192.168.1.7,local_lock=none,addr=192.168.1.8)

Any thoughts? I am getting nowhere on it.
