Extending AWS EBS volumes

Question

I have an EC2 instance running Ubuntu 18-04 LTS - Bionic-Ubuntu 18-04 2019, by default the instance was created with 8GB disk size.  Now I need to increase the disk size with no downtime (without restarting the machine).  As per the below information I need to increase the volume "/dev/nvme0n1p1"   
  
Please guide me how this can be done without rebooting the machine.  
  
Filesystem      Size  Used Avail Use% Mounted on  
udev            7.8G     0  7.8G   0% /dev  
tmpfs           1.6G  844K  1.6G   1% /run  
/dev/nvme0n1p1  7.7G  6.2G  1.6G  81% /  
tmpfs           7.8G   24K  7.8G   1% /dev/shm  
tmpfs           5.0M     0  5.0M   0% /run/lock  
tmpfs           7.8G     0  7.8G   0% /sys/fs/cgroup  
/dev/loop0       90M   90M     0 100% /snap/core/8268  
/dev/loop1       18M   18M     0 100% /snap/amazon-ssm-agent/1480  
/dev/loop2       90M   90M     0 100% /snap/core/8039  
tmpfs           1.6G     0  1.6G   0% /run/user/1000

Answer

you can refer the below blog for the powershell script that will extend the EBS volume by providing the drive letter, size to increase and instance name as an input and it will extend the EBS volume from AWS end as well as from OS end

Hello   
  
You need to do following to successfully increase volume size  
  
1. Increase volume size from AWS console   
  
    https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-modify-volume.html  
  
2. SSH into the instance.  
  
3. Extend the partition  
  
    $ sudo growpart /dev/nvme0n1 1  
  
4. Find out type of filesystem and extend it (use command appropriate to file system that you have)  
  
    $ sudo file -s /dev/nvme0n1p1  
  
Then please follow commands given in document https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/recognize-expanded-volume-linux.html (check section extending file system) to find the commands related to ext and xfs file systems.
