Can you tell us  more?  How did you do the  unmounts?
What "root" do you mean?
You mean a zfs root file system?  If so, the unmount of
the root file system should have failed.

Lori,

I have 4 disks on a SAN that I have created one pool on (IBM-ES7), when I
unmount any of these mount points (zfs umount /downloads) and then go to
/downloads I can still see the data.. then when I do a "zfs mount -a"
it says
cannot mount ''/downloads'': directory is not empty.

I can get it remounted using "zfs mount -O -a" but it doesn''t
make sence.

Example:

IBM-ES7/downloads    28707840 4691392 21431773    18%    /downloads

When all mounts are unmounted and I do a "du -sh /*|more" I still see
the space allocated. I would think this is filling up my root Filesystem based
on this output.

 3.7G   /downloads

Your thoughts..

I don''t have an answer for this.  In your first description
of the problem, it sounded like this had something to do
with a zfs root file system (which is my area of work), but
it doesn''t.

Maybe someone else can help you here.  My suggestion
in the meantime is to show a more complete series of
the commands you issued, with copious "zfs list" and
"zfs mount" commands sprinkled through the output.
Offhand, it looks like the zfs umount failed for some reason,
but I don''t see why.
