Ceph RGW_BUCKET_NOT_FOUND

A requested bucket does not exist in the RADOS Gateway.

Understanding Ceph and Its Purpose

Ceph is an open-source storage platform designed to provide highly scalable object, block, and file-based storage under a unified system. It is widely used for its reliability, scalability, and performance. Ceph's RADOS Gateway (RGW) is an object storage interface that provides applications with a RESTful gateway to the RADOS distributed object store, making it compatible with Amazon S3 and OpenStack Swift APIs.

Identifying the Symptom: RGW_BUCKET_NOT_FOUND

The error code RGW_BUCKET_NOT_FOUND is encountered when a requested bucket does not exist in the RADOS Gateway. This typically occurs when an application or user attempts to access a bucket that has been deleted or was never created.

Common Observations

  • Applications failing to retrieve or store objects in a specific bucket.
  • Error messages indicating that the bucket cannot be found.
  • Inability to list objects within the bucket.

Explaining the Issue: Why Does RGW_BUCKET_NOT_FOUND Occur?

The RGW_BUCKET_NOT_FOUND error is a clear indication that the bucket name specified in the request does not match any existing bucket in the RADOS Gateway. This can happen due to several reasons:

  • The bucket was deleted intentionally or accidentally.
  • The bucket name was misspelled in the request.
  • The bucket was never created in the first place.

Impact of the Issue

This issue can disrupt application workflows that rely on the bucket for storing or retrieving data, leading to potential data access failures and application errors.

Steps to Fix the RGW_BUCKET_NOT_FOUND Issue

To resolve the RGW_BUCKET_NOT_FOUND error, follow these steps:

Step 1: Verify the Bucket Name

Ensure that the bucket name specified in your application or command is correct. Double-check for any typographical errors. You can list all existing buckets using the following command:

radosgw-admin bucket list

This command will display a list of all buckets available in the RADOS Gateway.

Step 2: Recreate the Bucket if Necessary

If the bucket does not exist, you may need to recreate it. Use the following command to create a new bucket:

aws s3 mb s3://your-bucket-name --endpoint-url=http://your-rgw-endpoint

Replace your-bucket-name with the desired bucket name and your-rgw-endpoint with your RADOS Gateway endpoint.

Step 3: Update Application Configurations

Ensure that any application configurations or scripts that reference the bucket are updated with the correct bucket name. This includes configuration files, environment variables, and code references.

Additional Resources

For more information on managing buckets in Ceph, refer to the official Ceph RADOS Gateway Documentation. You can also explore the Ceph S3 API Documentation for details on bucket operations.

By following these steps, you should be able to resolve the RGW_BUCKET_NOT_FOUND error and ensure smooth operation of your Ceph-based applications.
