In 12 drive example above, with MinIO server running in the default configuration, you can lose any of the six drives and still reconstruct the data reliably from the remaining drives.

## Why is Erasure Code useful?

// minioMetaTmpDeletedBucket + unique uuid,
// Note that set distribution is ignored so it should only be used in cases where
// data is not distributed across sets. Errors are logged but individual
// disk failures are not returned.

							NoAuditLog:        true,

						rebalanceLogIf(ctx, err)
						failure = true
