adding free space to LVM

I replaced 146GB drives with 300GB drives in a HP server and extended the Raid 5 partition using HP smart array manager. I now have a 900GB HP Raid array logical volume and want to use the free space in CentOS 7 with LVM.

I want to allocate the free space to my home filesystem. What is the best way to accomplish this? I thought about trying to use fdisk to change the ending sector for partition 2 to have it end at 900 instead of 450. I know I could create a new partition with the free space and add it to the LVM group. Then add that to the filesystem. I'm not sure what is the best approach so thought I would ask the group. Thanks!

This is the output of parted and fdisk.
