MinIO is a high-performance, distributed object storage system designed to handle large-scale data storage needs. It is compatible with Amazon S3 cloud storage service and is often used for building cloud-native applications, data lakes, and machine learning models. MinIO is known for its simplicity, scalability, and high performance, making it a popular choice for developers and IT professionals.
When using MinIO, you might encounter an error message indicating an InvalidStorageClass. This error typically occurs when you attempt to specify a storage class that MinIO does not support. The error message might look like this:
Error: InvalidStorageClass: The specified storage class is not supported.
This error prevents the successful execution of your storage operations, such as uploading or retrieving objects.
MinIO supports a limited set of storage classes, primarily focusing on simplicity and performance. The most commonly supported storage classes in MinIO are:
If you specify a storage class outside of these supported options, MinIO will return the InvalidStorageClass error.
First, ensure that you are using a supported storage class. Check your configuration or the API request to confirm that the storage class is either STANDARD or REDUCED_REDUNDANCY.
// Example of setting a storage class in a MinIO client
minioClient.putObject('my-bucket', 'my-object', 'file.txt', {
'StorageClass': 'STANDARD'
});
If you find that an unsupported storage class is being used, update it to one of the supported classes. Modify your application code or configuration files to reflect this change.
After making the necessary changes, test your setup to ensure that the error is resolved. Try uploading or retrieving an object to verify that the InvalidStorageClass error no longer occurs.
