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.

Please, make sure you have backups before that. There is a way of backing up the partition table with gdisk. Look into it so you can restore it if anything goes wrong.

You need to use LVM to add this new disk to your volume group and then you can extend your logical volume.
