VMware workstation player - resize Ubuntu partition size

Shutdown your virtual machine and then open VMware workstation player > Click on the virtual machine name > Edit virtual machine settings.

Click on Disks and click expand button, enter a size for the new disk size and click ok. This will enable the workstation player to know the new hard disk size but the operating system ( Ubuntu ) running inside the vmware player doesn't know about it, therefore proceed to next step.

The easiest step, just download from https://gparted.org/download.php the latest available version.

Now we want to boot the virtual machine from the gparted iso downloaded in step 2 above but the problem is that as soon as we start the virtual machine it goes to run the ubuntu installed operating system & we don't have enough time to goto bios settings and change boot order.

We need to increase the delay time boot menu is displayed for the virtual machine. While the virtual machine is stopped (must be), goto its directory on your host computer and open a file ending with .vmx extension (usually virtual machine name + vmx extention) and add the following line at the end.

bios.bootDepaly = "10000"

This will show the boot menu of your virtual machine for 10 seconds.

Now again open the settings for your virtual machine and set the Optical disk to use iso file (instead of physical drive), check Connect on boot, save and start virtual machine.

Now you will see a timeout of 10s, just press F2 and you will see the famous bios setup screen, scroll to boot order and make CD/Drive the first option, F10.

Now once you successfully start the VM following the previous step, you will see gparted screen, press OK unless you see the GUI screen, click the tool icon to open it. Now you will see two sections one a yellow coloured and the second gray colored. Here as you can guess the yellow is the used space while the gray is the unused. Simply right click the yellow area and select resize/move option. In the next screen drag either the arrow after the yellow area or place a 0 in the box saying leave space after. 

This will make the operating system know that now the disk is increased and the volume can use the remaining free space. But not yet actually so proceed to the last practical step.

After the above step in gparted, exit gpart and reboot VM. Now once you login in the terminal or GUI of VM, open terminal and check disk space:

df -h

You will see the used space by your volume and in front of it the available space which is not yet increased. Therefore run the following command to see the free space of the Volume Group.

sudo vgdisplay

At the end of the output from the above command you will see something `FREE PE/SIZE ` and this is the fee space recognized by your VM. Now lets make use of it.

We need to display the Logical Volume information, run:

sudo lvdisplay

It  will show how much spache the logical volume is using actually and note the LV path as we will use it in the following command:

sudo lvextend -l +100%FREE /dev/ubuntu-vg/ubuntu-lv

This command tell VM to use all the available space for our logical volume. The path may differ so use the one that you see in the command above(lvdispaly).

Now run again command `df -h ` and note the disk path /dev/mapper/something and use this path in the following command as:

sudo resize2fs /dev/mapper/ubuntu--vg-ubuntu--lv

And finally check by running `df -h` that the logical volume now successfully use the available space.

Congratulations !!!
