Hi Avati,
    After upgrading to patch-123, all I did was start copying files  
around and then noticed that I can't overwrite any file. My shell  
thinks that the file is a directory when it is not. I just did  
another test:

[root at node01 www]# touch hi
[root at node01 www]# touch hi2
[root at node01 www]# cp hi2 hi
cp: overwrite `hi'? yes
cp: cannot create regular file `hi': No such file or directory

[root at node01 www]# mv hi2 hi
mv: overwrite `hi'? yes

[root at node01 www]# cp hi hi2
[root at node01 www]# ls -l hi*
-rw-r--r--  1 root root 0 Apr 26 08:22 hi
-rw-r--r--  1 root root 0 Apr 26 08:23 hi2

[root at node01 www]# rm hi
rm: remove regular empty file `hi'? yes
[root at node01 www]# rm hi2
rm: remove regular empty file `hi2'? yes
[root at node01 www]#


So you see, it is just the cp/overwrite which fails. This happens on  
nodes 2-4 also.
***After reverting to patch 119, all the above commands work fine***

Here are the conf files for glusterfs/glusterfsd I am using....

There are 4 servers and 4 clients.
