I need to expand the /home partition in my AWS EC2 instance. I have already added the required storage and trying to follow the article : https://docs.aws.amazon.com/ebs/latest/userguide/recognize-expanded-volume-linux.html

I need to extend the /home partition to its maximum.
When I run the command
# growpart /dev/xvda 7
I get the error
attempt to resize /dev/xvda failed. sfdisk output below:
| sfdisk: Warning: extended partition does not start at a cylinder boundary.
| DOS and Linux will interpret the contents differently.

I am using “CentOS Linux release 7.1.1503 (Core)”
I have also gone through : AWS EC2: error expanding EBS volume partition but this also did not work for me
How to extend the /home partition ?
