If you check from another computer is the file lost or not ?

Can you check the fid of the file (fs getfid file) on the computer where
the file exist.

   # fs getfid /afs/e.kth.se/home/staff/lha/.Xauthority 
   Fid: 536917885.9626.215976 in e.kth.se (212)

In the case where it doesn't exist its a little bit harder
to find the fid: do a strings on alla */*@ files in the cache directory

   # for a in */*@ ; do strings $a | grep Xauth && echo $a ; done
   .Xauthority
   08/9F@
   .Xauthority
   08/A0@

Now you run the afsdir_check from the arlad build directory (it isn't
installed)

   # /scratch/arla-0.34.6pre1/arlad/afsdir_check -v -- 08/9F | grep Xauth
   .Xauthority - 9626.215976


Note that the two last numbers in the fid should match the number
(9626.215976) from afsdir_check.

If they match, I would like to see some arlad traces when you try to access
the file.
