In the AWS EC2 console navigate to EC2 > Volumes and select the particular volume. Then select Modify volume from the Actions menu.
Set the new size and click Modify.
Since we are increasing the size of the volume, we must extend the file system to the new size of the volume. We can only do this when the volume enters the optimizing state. The modification might take a few minutes to complete.
Once the modification is completed, we log into the instance via SSH and resize the corresponding device.
Let’s verify the file system and type of the volume (in our example it is the root file system):
admin@srv:~$ df -hT

udev devtmpfs 223M 0 223M 0% /dev

tmpfs tmpfs 47M 0 47M 0% /run/user/1000To check whether the volume has a partition that must be extended, we use the lsblk command:
admin@srv:~$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
nvme0n1 259:0 0 10G 0 disk
|-nvme0n1p1 259:1 0 8.9G 0 part /

`-nvme0n1p15 259:3 0 124M 0 part /boot/efiWe use the growpart command to extend the first partition:
admin@srv:~$ sudo growpart /dev/nvme0n1 1

admin@srv:~$ sudo resize2fs /dev/nvme0n1p1

Filesystem at /dev/nvme0n1p1 is mounted on /; on-line resizing required

admin@srv:~$ df -hT /dev/nvme0n1p1
