Beware that any mistake (including one that I might have made answering) can destroy part or all of your data so backup anything you want to preserve before running these commands.

sorry, bt i think since i left the 4G upon the installation, i did not maximize the whole 25G since i just 21G to my /,/export/home,swap etc..

i can not use it anymore anyway thanks for the great help//
