  1. Stopped the instance

    Thank you Wilman your commands worked correctly, small improvement need to be considered if we are increasing EBSs into larger sizes

    1. Stop the instance
    2. Create a snapshot from the volume
    3. Create a new volume based on the snapshot increasing the size
    4. Check and remember the current's volume mount point (i.e. /dev/sda1)
    5. Detach current volume
    6. Attach the recently created volume to the instance, setting the exact mount point
    7. Restart the instance
    8. Access via SSH to the instance and run fdisk /dev/xvde

      WARNING: DOS-compatible mode is deprecated. It's strongly recommended to switch off the mode (command 'c') and change display units to sectors (command 'u')

    9. Hit p to show current partitions

    10. Hit d to delete current partitions (if there are more than one, you have to delete one at a time) NOTE: Don't worry data is not lost
    11. Hit n to create a new partition
    12. Hit p to set it as primary
    13. Hit 1 to set the first cylinder
    14. Set the desired new space (if empty the whole space is reserved)
    15. Hit a to make it bootable
    16. Hit 1 and w to write changes
    17. Reboot instance OR use partprobe (from the parted package) to tell the kernel about the new partition table
    18. Log via SSH and run resize2fs /dev/xvde1
    19. Finally check the new space running df -h
