mounted directories on OS X

I cannot cd into directories that are mounted from the network, the
error message being

??? Error using ==> cd
Cannot CD to /data (Name is nonexistent or not a directory

even though I cd cd into /data in the X11-shell. Any Idea what to do?

Use...

cd '/Volumes/data'

(i.e., /Volumes is the mount point)

I get the exact same failure message on my /home, which is not NFS
mounted. It is a completely normal ext3 drive. df says:

/dev/hda4 ... ... ... 96% /home

I wondered whether the 96% fill might be a problem. But I have no
problem creating files and browsing through the file system with
other programs.

The really mysterious thing is, that cd actually changes directory
the way I ask it to. And ls shows the correct list of directory
content. But the graphical directory listing doesn't work, and Matlab
refuses to run any scripts in the directory.

The problem only arises on my /home drive. There is no problem on /
or on my plenty of NFS mounted drives.

By the way: Fedora Core 2 running Linux 2.6.5. Matlab 7.0.1.24704.

I had the exact same problem as below:

This was on Mac OS X 10.3.9, using R14, both SP1 and SP2.
This was running from my home directory, mounted at /home from a Mac
OS X Server 10.3.9 machine.

The half-fix was to make a softlink from /automount/static/home to
/automount/home. This works sometimes. However, I still have the
problem when Matlab randomly decides to pre-pend /private to the
path: 
ans =
/automount/home/ianfasel/SCTL/MPTX/Flonk

Things here work normally, however if the file is in a subdirectory:
 
/private/automount/home/ianfasel/SCTL/MPTX/Flonk/RNDerivatives/bootstr
ap.m
(notice /private here but not above)
Then matlab won't notice changes to files in this directory and it is
necessary to type 
to get it to run the files as they exist on disk rather than run them
from cache.

Here's another weird example:
 
ans =
/automount/home/ianfasel/SCTL/MPTX/Flonk 
/private/automount/home/ianfasel/SCTL/MPTX/Flonk/RNDerivatives/bootstr
ap.m 
/automount/home/ianfasel/SCTL/MPTX/Flonk/RNDerivatives/bootstrap.m

Notice that when I change into the directory where the file is
located, /private is no longer part of the pathname. If I run
'bootstrap' from the original directory, matlab does not notice
changes to the file. However if I cd into the directory, it now
notices changes.

Perhaps it has something to do with the pathnames I used when I added
the path?

One more observation... There is a difference between R14 and R14sp2
apparently. In R14, if I add a path, the relative pathname is used
when I type 'which'. In R14sp2, the full pathname is used when I use
which.

Example 1: (This works correclty -- i.e., changes to files are
noticed)...
% /Applications/MATLAB7/bin/matlab -nojvm -nosplash
Xlib: extension "GLX" missing on display "localhost:10.0".
??? Not able to create a render context.

Now I see, that when I am actually standing in /home/macw, Matlab
thinks I am standing in /usr/local/macw:
 

ans =

/usr/local/macw

This probably has something to do with the installation path of
Matlab (/usr/local/matlab14). May it could also have something to do,
with the way I installed Matlab. Since I was short of space on my
/usr/local, I installed Matlab in /home/matlab14 and symlinked that
to /usr/local/matlab14.

I have no idea about how to work around this problem.
