I forgot to outline zaxxon's remark: mounting filsystems on filesystems can bring up issues like if the mounting order isnt respected, you have weard behaviour:
We have
/opt/oracle
/opt/oracle/product/ #directory for all the versions mountpoints
/opt/oracle/product/8.1.6 #just for the example.
It happened once on a AIX that /opt/oracle/product/8.1.6 got mounted first
then
/opt/oracle ...
The dbas were in panic because they thought they had lost (a bad rm ????) their software
They started to restore in /opt/oracle all the missing product, at the time I came in.
And after looking at df I told them to stop, umounted /opt/oracle, /opt/oracle/product/8.1.6
Then mounted in correct sequence.
All was there...
This is to say beware of people that can create the path on /
The above situation should never have occured (well not that way...): If no one had created /opt/oracle/product/8.1.6 in / that filesystem could not mount till /opt/oracle was...

fs_whereis
FS_WHEREIS(1) AFS Command Reference FS_WHEREIS(1)
NAME
fs_whereis - Reports each file server housing a file or directory
SYNOPSIS
fs whereis [-path <dir/file path>+] [-help]
fs whe [-p <dir/file path>+] [-h]
DESCRIPTION
The fs whereis command returns the name of each file server machine that houses the volume containing each directory or file named by the
-path argument.
OPTIONS
-path <dir/file path>+
Names each AFS file or directory for which to return the host file server machine. Partial pathnames are interpreted relative to the
current working directory, which is also the default value if this argument is omitted.
-help
Prints the online help for this command. All other valid options are ignored.
OUTPUT
The output includes a line for each specified directory or file. It names the file server machine on which the volume that houses the
specified directory or file resides. A list of multiple machines indicates that the directory or file is in a replicated volume.
Machine names usually have a suffix indicating their cell membership. If the cell is not clear, use the fs whichcell command to display the
cell in which the directory or file resides. To display the cell membership of the local machine, use the fs wscell command.
EXAMPLES
The following example indicates that volume housing the directory /afs/abc.com resides is replicated on both "fs1.abc.com" and
"fs3.abc.com":
% fs whereis -path /afs/abc.com
File /afs/abc.com is on hosts fs1.abc.com fs3.abc.com

None
