I'm trying to extend my hard disk, but it doesn't work correctly. According to many suggestions on the internet, I ran this command:

$ sudo lvresize --extents +100%FREE --resizefs WWW-vg/root
  Size of logical volume WWW-vg/root unchanged from 47.52 GiB (12165 extents).
  Logical volume root successfully resized.
resize2fs 1.42.13 (17-May-2015)
The filesystem is already 12456960 (4k) blocks long.  Nothing to do!

I also tried this command:

$ sudo lvextend -l +100%FREE WWW-vg/root
  New size (12165 extents) matches existing size (12165 extents)
  Run élvextend --help' for more information.

I'm sure, I've added the hard disk because when run lsblk, I'll get this output:

NAME               MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT

├─sda2               8:2    0    1K  0 part 
└─sda5               8:5    0 49.5G  0 part

sr0                 11:0    1 1024M  0 rom

It's confusing to me why the size of the sda is 110G but the sum of sda1,sda2,sda5 is 50G. Where is another 60G? How can I add this 60G to my WWW--vg-root?

Here's some information about my device that I hope they help.
