How to extend disk space in the current partition (with cmdlets)

  • 772

I have my current partition disk space (found at /dev/mapper/cl-root) set at 50Go on my CentOS server. I want to extend the current disk space (to become 500Go) used in a neat way with commands.

How to do it ?

UPDATE : parted -l lsblk returns /dev/sda, /dev/sdb, /dev/sdc actual sizes and other infos. But what i want is to extend the root partition under /dev/mapper/cl-root which is listed among others with fdisk -l cmd enter image description here enter image description here enter image description here

    After evaluating the output of commands and the comments, you need:
    (execute these commands as a sudoer user, adding sudo in front or as root)

    parted /dev/sda mklabel gpt
parted -a opt /dev/sda mkpart lvm 0% 50%
pvcreate /dev/sda1
vgextend cl /dev/sda1
lvextend -r -l 100%VG cl/root
