How to increase Volume size on EC2 instance

Increasing the storage volume size of your Ubuntu EC2 instance on AWS involves a few steps. Here’s a step-by-step guide to help you:

Step 1: Modify the Volume

1. Go to the EC2 Dashboard: Sign in to the AWS Management Console, open the EC2 dashboard.

2. Navigate to Volumes: In the left-hand menu, under 'Elastic Block Store', click on 'Volumes'.

3. Select Your Volume: Find the volume attached to your instance. It will typically have an 8GB size.

4. Modify Volume: Right-click on the volume and select 'Modify Volume'.

5. Increase Size: In the 'Size (GiB)' field, enter '32' to increase the size to 32GB.

6. Apply: Click 'Modify'. It may take a few moments for the changes to take effect.

Step 2: Extend the File System

After increasing the volume size, you need to extend the file system on your instance.

1. Connect to Your Instance: Use SSH to connect to your EC2 instance.

   bashCopy codessh -i your-key.pem ubuntu@your-instance-public-dns

2. Verify the Volume Size: Check if the volume size has been increased.

   bashCopy codelsblk

   You should see the increased size for your root volume (e.g., /dev/xvda1).

3. Extend the File System: Depending on the file system type, you’ll use different commands. For ext4 or ext3 file systems:

   bashCopy codesudo resize2fs /dev/xvda1

   For xfs file systems:

   bashCopy codesudo xfs_growfs -d /

4. Verify the New Size: Check that the file system now uses the increased space.

   bashCopy codedf -h

Example Commands:

Here's a summary of the commands you might run on your instance:

bashCopy code# Connect to your EC2 instance
ssh -i your-key.pem ubuntu@your-instance-public-dns

# Verify the current disk layout
lsblk

# Resize the file system (for ext4/ext3)
sudo resize2fs /dev/xvda1

# Or, resize the file system (for xfs)
sudo xfs_growfs -d /

# Verify the new file system size
df -h

By following these steps, you should be able to successfully increase the storage volume size of your Ubuntu EC2 instance from 8GB to 32GB.

It looks like the volume size has been increased to 32GB, but the partition /dev/xvda1 is still 7GB. You need to extend the partition before resizing the file system.

Here are the steps to extend the partition and resize the file system:

Step 1: Install growpart and cloud-guest-utils

Ensure you have growpart and cloud-guest-utils installed. These tools help in resizing the partition.

bashCopy codesudo apt-get update
sudo apt-get install cloud-guest-utils

Step 2: Extend the Partition

Use growpart to extend the partition /dev/xvda1 to occupy the additional space.

bashCopy codesudo growpart /dev/xvda 1

Step 3: Resize the File System

Now resize the file system to use the newly available space.

For ext4 or ext3 file systems:

bashCopy codesudo resize2fs /dev/xvda1

For xfs file systems:

bashCopy codesudo xfs_growfs -d /

Step 4: Verify the New Size

Finally, verify that the file system has been resized to use the new space.

bashCopy codedf -h

Example Commands:

Here’s a summary of the commands you might run:

bashCopy code# Update package list and install necessary tools
sudo apt-get update
sudo apt-get install cloud-guest-utils

# Extend the partition
sudo growpart /dev/xvda 1

# Resize the file system (for ext4/ext3)
sudo resize2fs /dev/xvda1

# Or, resize the file system (for xfs)
sudo xfs_growfs -d /

# Verify the new file system size
df -h

After running these commands, your root partition /dev/xvda1 should occupy the full 32GB space available on the volume.
