Partition table entries are not in disk order.

Hey,

When we need to expand EC2 instance storage of an EC2 instance, extending volume size in AWS management console is not enough, It just increases the overall size of the drive wheas we can create that extra size as another partition on disk or extend existing root partition as per the ask in the task.
Here is how we can achive it:

  1. Extend volume size using AWS console
  2. Login to EC2 instance using ssh
  3. lsblk → list partition blocks
  4. sudo xfs_growfs /dev/xvda 1 → extend partition size by identifying it’s block
  5. lsblk → verify partition blocks
  6. df -h → verify optional
