Note: For the latest and complete guideline, follow the official such as this.
1. Configure AWS Access Key
Follow here.
2. Set credentials for AWS CLI
$ aws configure
AWS Access Key ID [None]: ******************UD
AWS Secret Access Key [None]: ******************IX
Default region name [None]: ap-northeast-1
Default output format [None]: json3. Check which hypervisor the instance is based on (i.e. Xen or Nitro), since device and partition naming differs
$ aws ec2 describe-instance-types --instance-type t2.micro --query "InstanceTypes[].Hypervisor"
["xen"]4. Check whether the volume has a partition (use lsblk command)
$ sudo lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
xvda 202:0 0 20G 0 disk
└─xvda1 202:1 0 12G 0 part /5. Extend the partition (use growpart command: specify the device name and the partition number)
$ sudo growpart /dev/xvda 1
CHANGED: partition=1 start=4096 old: size=25161695 end=25165791 new: size=41938911 end=419430076. Verify that the partition has been extended (use lsblk command: the partition size should now be equal to the volume size)
$ sudo lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
xvda 202:0 0 20G 0 disk
└─xvda1 202:1 0 20G 0 part /7. Get the name, size, type, and mount point for the file system that you need to extend (use df -hT command)
$ df -hT

tmpfs tmpfs 98M 0 98M 0% /run/user/10008. Perform the extension of the mounted file system
Now that we know the file system is xfs, on which the root dir is mounted, then use xfs_growfs command to specify the mount point of the file system to be extended.
$ sudo xfs_growfs -d /
