How to Extend Hard Disk on CentOS 7 type Partition 83 Linux

Preparation

Step 1: Check Your Current Disk Space

Before diving into the process of extending the hard disk, it's essential to understand your system's current disk space usage. To do this, open the terminal and enter the following command:

# df -h

This command will display a list of mounted filesystems along with their disk usage details. Identify the partition you wish to extend (Partition 83) and take note of the available space.

# lsblk

Check Your Current Disk Space

Step 2: Take a Backup

Manipulating disk partitions can be risky, so it's crucial to create a backup of your important data before proceeding. If anything goes wrong during the process, you'll have a safeguard to fall back on.

There are many ways to back up your data, but in this case, I am backing up the entire OS using Synology NAS because I will be making changes on the OS side.

Step 3: Download Gparted

In this tutorial, I will be using a widely used tool called Gparted. You can download it here first. 

After downloading, you can directly upload it to ESXi, where the VM that needs the additional hard disk is located. We will perform the addition using a live CD and require booting with the Gparted ISO.

Step-by-Step Guide

Step 1: Adding disk space in VMware

Next, we'll take action in VMware by increasing the size of the hard disk 1. Enter the required size; for example, I'll raise it from 10 GB to 20 GB.

In the VMware vSphere Client : select your ESXi VM CentOS 7 and go to "Edit Settings." Locate the virtual disk you want to extend and increase its size.

Step 2: Mount gparted.iso in VMware

Now, the next step is to mount the downloaded Gparted Live ISO into the CentOS 7 OS, where we will add the additional hard disk. Follow these steps:

In the VMware vSphere Client : click CD/DVD Media - choose Datastore ISO File - choose gparted-live-1.5.0-1-amd64.iso - checklist Connected

Step 3: Setup first boot in VMware

The final step we need to perform in your ESXi or VCenter is to change the first boot settings in your VM.

In the VMware vSphere Client : click Tab VM Options  - Expand Boot Options - on Force BIOS setup checklist During the next boot, force entry into the BIOS setup screen - click OK

Step 4: Restart the system and perform the configuration using the Gparted Live ISO.

Open the terminal and hit this command to restart the system.

# reboot

And reopen your vCenter and Launch Remote Console setup boot to CD-ROM Drive.

choose tab Boot - Move the CD-ROM Drive to the top - Save and Exit press F10 - Setup Confirmation Choose Yes

Restart the system and perform the configuration using the Gparted Live ISO

Step 5: Launch GParted Live

Step 6: Configure in GParted Live

Wait until the process is complete, and a new window appears. Then, select the drive we added earlier, which has a capacity of 20 GB or /dev/sdb. In there, you will find 2 disks that have been allocated as /dev/sdb1 or mounted in my OS as /kitsake partition, and there is 10 GB of unallocated space.

Click on disk and choose /dev/sdb

select the drive

Now, we will add this unallocated space to /kitsake. Right-click on /dev/sdb1 in the displayed list.

select /dev/sdb1 - and thent Right Click - Choose Resize/Move

Right-click on /dev/sdb1 in the displayed list, then choose Resize/Move

After that, move the slider to the right to allocate all the available sizes to /dev/sdb1. 

move the slider to the right - then click Resize/Move

Then, click Resize/Move.

On the green checkbox logo, click directly to apply the changes we made above.

Exit from gparted live

A notification will appear: "Please remove the live medium, close the tray (if any), and press ENTER to continue."

Please remove the live medium, close the tray (if any), and press ENTER to continue

Now, go to vCenter

Right click on the CentOS 7 VM, select the Virtual Hardware tab - and in the CD/DVD drive option, change it to Client Device - Click OK.

Unmount CD-ROM

Next, open the console again and press enter. Then, wait for the booting process to finish until the OS starts up.

Check Capacity After Added Extend Hard Disk

And that's it! You can now check the modified disk by following the steps below:

# df -h
# lsblk

Check Your Disk Space After Added Size

That's how to extend a Hard Disk on CentOS 7 type Partition 83 Linux. Don't forget to try it in a development environment first before implementing it in the production environment. And always make a backup before making any changes, just to be safe.
