## Pre-pre requisite

- A working knowledge of MinIO codebase and its various components.
- A working knowledge of AWS S3 API behaviors and corner cases.

## Pre-requisite for backporting any fixes

Fixes that are allowed a backport must satisfy any of the following criteria's:

}

// StorageFull storage ran out of space.
type StorageFull struct{}

func (e StorageFull) Error() string {
	return "Storage reached its minimum free drive threshold."
}

// SlowDown  too many file descriptors open or backend busy .
type SlowDown struct{}

func (e SlowDown) Error() string {
	return "Please reduce your request rate"
}

)

// Refer http://docs.aws.amazon.com/AmazonS3/latest/dev/NotificationHowTo.html#notification-how-to-event-types-and-destinations
// for most basic values we have since extend this and its not really much applicable other than a reference point.
// "s3:Replication:OperationCompletedReplication" is a MinIO extension.
