# Federation Quickstart Guide [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io) *Federation feature is deprecated and should be avoided for future deployments*

This document explains how to configure MinIO with `Bucket lookup from DNS` style federation.

## Get started

### 1. Prerequisites

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

### 2. Run MinIO in federated mode

		// Preserve older credential if we do not have
		// root credentials set via environment variable.
		globalActiveCred = cfg.Credential
	}

	// Init compression config. For future migration, Compression config needs to be copied over from previous version.
	switch cfg.Version {
	case "29":
		// V29 -> V30
		cfg.Compression.Enabled = false

			}
		}
	}()

	return quorumLocked
}

// checkFailedUnlocks determines whether we have sufficiently unlocked all
// resources to ensure no deadlocks for future callers
func checkFailedUnlocks(locks []string, tolerance int) bool {
	unlocksFailed := 0
	for lockID := range locks {
		if isLocked(locks[lockID]) {
			unlocksFailed++
		}
	}

	h.storeCtxCancel()

	// Wait for messages to be sent...
	h.wg.Wait()

	// Set logch to nil and close it.
	// This will block all Send operations,
	// and finish the existing ones.
	// All future ones will be discarded.
	h.logChMu.Lock()
	xioutil.SafeClose(h.logCh)
	h.logCh = nil
	h.logChMu.Unlock()
