From your comment /dev/sda2 is around ~8GB (since it looks like fdisk uses 1KiB sector, but I'm not sure about that)

/dev/sda: 64.0 GB, 63962087424 bytes, 124925952 sectors



Device      Boot    Start       End         Sectors     Size    Id Type

/dev/sda1   *       2048        1026047     512000      83      Linux

/dev/sda2           1026048     16777215    7875584     8e      Linux LVM

Just run gparted to resize /dev/sda2 to the end of the hard drive, and then resize your LVM partition. For more information about resize LVM partition read How can I resize an LVM partition? (i.e: physical volume)

Here is the result [root@localhost ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/centos-root 6.7G 5.5G 1.3G 82% / Still wondering how do get to use the 60 GB, which is not showing in any of the disk usage?

  @truthtriumphs did you resize /dev/sda2 as I said? Because 6.67 GiB (1707 extents) to 6.71 GiB (1717 extents) looks like the partition is still the same size, so LVM can't resize it any bigger than that
