# 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.

   ```bash
   bashCopy codessh -i your-key.pem ubuntu@your-instance-public-dns
   ```
2. **Verify the Volume Size**: Check if the volume size has been increased.

   ```bash
   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:

   ```bash
   bashCopy codesudo resize2fs /dev/xvda1
   ```

   For `xfs` file systems:

   ```bash
   bashCopy codesudo xfs_growfs -d /
   ```
4. **Verify the New Size**: Check that the file system now uses the increased space.

   ```bash
   bashCopy codedf -h
   ```

#### Example Commands:

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

```bash
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.

```bash
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.

```bash
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:

```bash
bashCopy codesudo resize2fs /dev/xvda1
```

For `xfs` file systems:

```bash
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.

```bash
bashCopy codedf -h
```

#### Example Commands:

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

```bash
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.
