Accessing free space on a Linux File system

Hello Blu,
    I wish to access free space on the end of a file system. There is a about 125G available. 
    I mounted the system from a install disk and the space is available.
    Working with Parted - I need START and END coordinates to partition the space.

    What tools are available to find unpartitioned space and the coordinates to create a partition after installation.


[root@~]# df -h
