**>> Free PE / Size 5120 / 20.00 GiB
So Firstly we are extending volume group
# lvextend -l +5120 /dev/telekom_kutayzorlu_com-vg/root
After Resize to see Action in Disk Size Now
# resize2fs /dev/telekom_kutayzorlu_com-vg/root
If you are using XFS file format it will give error so use that
# xfs_growfs /dev/telekom_kutayzorlu_com-vg/root
