I had created a qcow2 image with Virtual Machine Manager on CentOS (150GB). Another CentOS 7 was installed along with WHM & cPanel in that image.
I have done some research and increase the qcow2 image's virtual size to 300GB.
qemu-img info (on HOST):
Now, I would like to increase the space inside the qcow2 image. I searched on Unix Stackchange and know that I should use Parted (My Parted version is 3.1) from this Question.
The directory I need more space is /home (Filesystem is /dev/mapper/centos-home). Its size is about 100GB right now, and I want to increase its size to 250GB. But then I think the device /dev/sda2 is what I should expand before increasing /home? What are the correct steps to increase the filesystem size for my scenario?
Here are some related info:
du -h (inside the image):
fdisk -l (inside the image):
