Sorry. There are reasons for multiple mounts. Bind for one.

Even better, next time try not stupidly mounting the filesystem
twice. :)

That might be a good feature request for mount. If the filesystem is
already mounted someplace, don't allow it to be mounted again, with an
error message to umount the other one first.

Guess what? Ubuntu repaired itself. I did nothing. But suddenly /mnt
appears properly with ls -la, and Thunar displays the filesystem again.
I don't know how this happened, but I'm not questioning it. 

Whew! Hooray!

Now on to trying to figure out rsync.

It might even have trouble rebooting.
I am just stabbing in the dark at this point but you can try
umount --lazy /media/jjj/Synology
umount --lazy /mnt

umount -i /media/jjj/Synology
umount: /media/jjj/Synology is not in the fstab (and you are not root)

I got the same message when I tried it on /mnt.

The only things in fstab are / and /home. 

I'm afraid to reboot. Rebooting will umount everything, except /
and /home will be remounted, so that should clear up part of the problem
with /mnt. But what about the missing permissions and other stuff?

It did not take well to your forced umount. Everything still thinks there
is something mounted at /mnt
Don't really know  how to solve this, but you can try
umount -i /media/jjj/Synology
umount -i /mnt
See if thunar is ok, then try to mount again where you want it.

Make sure any stale entries have been cleared from /etc/fstab and then reboot.

Not quite solved. After installing cifs-utils I ran the command, but I
didn't realize that the last time I ran the mount command I was trying
to mount it in /mnt - so that is where it mounted it. Realizing my
error I ran the command again and mounted it in /media/jjj/Synology. So
then I needed to umount it from /mnt, but the umount command didn't
like that:

jjj@Devil-Bonobo:/media/jjj$ umount //synology.local/synology/
umount: it seems //synology.local/synology/ is mounted multiple
times

I solved this problem with the -f (force) option. That umounted it from
both places. Then I remounted it just in /media/jjj/Synology. I thought
all was solved but now Thunar won't display the filesystem. The error
message is 

Failed to open directory "Filesystem"
Error when getting information for file '/mnt': No such device.

I tried mkdir /mnt, but I got 'cannot create directory '/mnt': File
exists.'

Now what?
