EC2 - increase storage without turn off instance

[aizu]

To increase the space on your AWS instance, follow these steps:

1. Check the Available Storage:
Before expanding, verify the disk space:

df -h

2. Identify the Volume:
Find the attached volumes for your EC2 instance:

Go to the EC2 Console.
Under Elastic Block Store (EBS), select Volumes.
Identify the volume attached to your instance.

3. Modify the EBS Volume:
Select the volume you want to expand.
Click on Actions → Modify Volume.
Increase the size of the volume (e.g., from 8 GB to 20 GB).
Click Modify.

4. Extend the Partition on the EC2 Instance:
After the volume is resized, you'll need to extend the file system to use the new space.

For ext4 file system:
Verify the volume size:

lsblk

Make sure the resized volume reflects the correct size.
Extend the file system:

sudo growpart /dev/nvme0n1 1
sudo resize2fs /dev/nvme0n1p1

For xfs file system:
Extend the file system:

sudo xfs_growfs -d /

5. Verify the Increased Space:
Check the disk space again:

df -h

This process will allow you to increase the disk space without stopping the instance.

To check partition type

lsblk -f
