Enable object lifecycle configuration on buckets to setup automatic deletion of objects after a specified number of days or a specified date.

## 1. Prerequisites

- Install MinIO - [MinIO Quickstart Guide](https://min.io/docs/minio/linux/index.html#quickstart-for-linux).
- Install `mc` - [mc Quickstart Guide](https://min.io/docs/minio/linux/reference/minio-mc.html#quickstart)

## 2. Enable bucket lifecycle configuration

	// Make a volume entry on all underlying storage disks.

				afterState[index] = madmin.DriveStateOffline
				return errDiskNotFound
			}

			beforeState[index] = madmin.DriveStateOk
			afterState[index] = madmin.DriveStateOk
