Using Centos 6.4, how to inform the kernel that the /sda2 partition has increased


Am needing to enlarge the /dev/mapper/vg_xxx-lv_root size from a fixed size of 50G to 500G.
After cloning from a 300gb disk onto a 1tb disk, after using fdisk to delete the /sda2 partition & then creating that partition to end on the larger cylinder, gpartd does
see that the /sda2 partition as now being ~ 933gb in size.
The OS boots fine. How do I inform the kernel of this so that the /root can now be increased from its original limit of 50G? Using vgdisplay; shows the format is lvm2,
vg status is resizable,free pe/size is 0. When using the
resize2fs or lvextend or partprobe commands they each report that its at its maximum size? The jobs that run on these systems fill the /usr/scratch directory of 50gb real quick before completion.
What can I do to increase this volume size?
Again, Centos 6.4 is being used.

Thanks,

Wayne

Wow.... The file system is now at 493G...

Thanks so much for your quick response. The resize2fs command just finished. You got me outta' the
dog-house with many users. Now its time to do 35 more of these systems.

Thanks again..
