Apologize for taking this long to post my summary--I was waiting for a
good time to unmount all the file systems which include the users' home
directories. My thanks to all who responded:

Solutions:
1. On man:
I don't know how my windex got out-of-date but apparently that
was the culprit. Once I did a "catman -w" everything went fine.
I combined all the responses on this topic as follows:
This could be a case of "windex out of date". Try
man -F -s1m mount
If that works, then, as root
catman -w -M/usr/man
to rebuild windex.

Check the "cat1m" directory. Does it exist and have good perms?

1) The absolutely brute-force way you can use if all else fails is:
% nroff -man /usr/man/man1m/mount.1m | more -s
2) The "man -s 1m mount" command absolutely should have worked, *unless*
you've got a corrupted windex file. Try "man -F -s 1m mount". The
-F bypasses the windex file.
3) The "man -M /usr/man/man1m mount" command has an error, it should
be "man -M /usr/man mount". You can't choose sections with -M,
only with -s.
4) Most likely you need to do a "catman -w -M /usr/man", because someone
started it at one time and either did not let it finish, or managed
to corrupt the windex file (/usr/man/windex). By default, man
relies on the windex file, if it exists. You also could just remove
the windex file, but please don't do that (man -k won't work!).
In general, you need to be aware of all the places you have man pages
and make sure the windex files are updated when appropriate.
*****
It sounds like you're missing the proper windex files. I think
"/usr/lib/makewhatis /usr/man" will generate what you need.
*****
Check the environment variable MANPATH. This is the setting I use:
setenv MANPATH
/usr/local/man:/usr/share/man:/usr/openwin/share/man:/usr/local/lib/perl5/man
If it still doesn't work, you might want a better manpage viewer. There's
one called "woman" that I really like.

2. On mount:
I tested the commands "umountall -F nfs" and "umountall -r"
and both worked beautifully.
Other responses are:
Make sure there are no proceses running that reside on or write
to the file systems you wish to unmount. Be especially mindful
of the automounter - it will hold on to a file system for a
bit (i.e. /home after all users have "logged off").
*****
cp /etc/fstab /etc/fstab.old
umount and leave all the nfs fs inside.
umountall
and then you put the original fstab back ???
Thanks, everybody.
