Finding Large EBS Volumes in AWS with CLI

If you’re working with Amazon Web Services (AWS) on a regular basis, you may occasionally need to retrieve a list of Elastic Block Store (EBS) volumes that meet certain criteria. One common task is identifying EBS volumes that are >= 200GiB in size. However, using the AWS Command Line Interface (CLI) can sometimes yield unexpected results if commands are not formatted properly. In this guide, we'll explore how to effectively locate these large EBS volumes using AWS CLI.

The Issue at Hand

Many users encounter challenges when using the AWS CLI to filter EBS volumes by size. For example, one user ran the following command:

Unfortunately, this command returned no results, despite the user knowing that several volumes met the specified condition when checked in the AWS Management Console. This highlights how easy it can be to generate an empty result set due to incorrect command syntax.

The Solution: Correct AWS CLI Command

To successfully find EBS volumes of size >= 200GiB, you'll need to use the describe-volumes command with proper querying techniques. Here’s how you can do it step-by-step:

Step 1: Use the Correct Query Syntax

Instead of trying to filter directly on the size using the --filter flag, you should use the --query flag to get the desired information. The correct command format is:

Step 2: Breakdown of the Command Components

describe-volumes: This is the primary command to list all EBS volumes in your account.

--query: This option allows you to specify criteria for the output.

Volumes[?Size >= 200]: This part filters the volumes where the size is greater than or equal to 200GiB. It uses a JMESPath query expression.

.{tag:Tags, ID:VolumeId, size:Size, type:VolumeType}: This defines the output format, specifying that you want to see tags, volume ID, size, and the volume type.

Step 3: Execute the Command

Once you've formulated the command correctly, execute it in your AWS CLI environment. You should now see a list of EBS volumes that meet the >= 200GiB requirement.

Additional Tips for Effective CLI Usage

Check for typos: Small typographical errors can lead to commands failing to return results.

Use the AWS Documentation: AWS provides comprehensive documentation for CLI commands, which can be helpful for troubleshooting and understanding different options available.

Update CLI Version: Ensure that your AWS CLI is up to date, as command features may vary between versions.

Conclusion

Identifying AWS EBS volumes that meet certain size criteria can be done quickly and efficiently with the right command syntax in the AWS CLI. If you have ever experienced challenges retrieving this data, you now have the knowledge to correct command usage and achieve your goal. Happy querying!
