Hi Avati,

Hi Anand,

I'm testing GLfs using apache. I've written a small script which creates
random name file in /gfs-data/IOtest/php_test/ but instead on creating at
desire location it create it at default path, /gfs-data/. 

Flowing are client log for that particular file. 

"TestFile200802041624-270txt" file is not created at
/gfs-data/IOtest/php_test/. It got created at /gfs-data/
