### Homebrew (recommended)

Run the following command to install the latest stable MinIO package using [Homebrew](https://brew.sh/). Replace ``/data`` with the path to the drive or directory in which you want MinIO to store data.

```sh

          "expr": "minio_node_drive_used_bytes{job=~\"$scrape_jobs\",server=\"$server\"}",
          "interval": "",
          "legendFormat": "Used [{{drive}}]",
          "refId": "B"
        },
        {
          "datasource": {
            "type": "prometheus",
            "uid": "${DS_PROMETHEUS}"
          },
          "exemplar": true,

			// Fresh setup, wait for first server to be up.
			logger.Info("Waiting for the first server to format the drives (elapsed %s)\n", getElapsedTime())
		case errFirstDiskWait:
			// Fresh setup, wait for other servers to come up.
			logger.Info("Waiting for all other servers to be online to format the drives (elapses %s)\n", getElapsedTime())
		case errErasureReadQuorum:

	globalServiceFreezeCnt int32
	globalServiceFreezeMu  sync.Mutex // Updates.

	// List of local drives to this node, this is only set during server startup,
	// and is only mutated by HealFormat. Hold globalLocalDrivesMu to access.
	globalLocalDrives   []StorageAPI
	globalLocalDrivesMu sync.RWMutex

	globalDriveMonitoring = env.Get("_MINIO_DRIVE_ACTIVE_MONITORING", config.EnableOn) == config.EnableOn

	// Is MINIO_CI_CD set?

		Type:      gaugeMetric,
	}
}

func getClusterErasureSetHealingDrivesMD() MetricDescription {
	return MetricDescription{
		Namespace: clusterMetricNamespace,
		Subsystem: "health",
		Name:      "erasure_set_healing_drives",

	}

	// Fetch all the drive info status.
	beforeDrives := formatsToDrivesInfo(s.endpoints.Endpoints, formats, sErrs)

	res.After.Drives = make([]madmin.HealDriveInfo, len(beforeDrives))
	res.Before.Drives = make([]madmin.HealDriveInfo, len(beforeDrives))
	// Copy "after" drive state too from before.
	for k, v := range beforeDrives {
		res.Before.Drives[k] = v
		res.After.Drives[k] = v
	}

	if hr.Before.Drives[0].State != madmin.DriveStateMissing {
		t.Fatalf("Unexpected drive state: %v", hr.Before.Drives[0].State)
	}

	// Check the state of all other disks (should be ok)
	for i, h := range append(hr.Before.Drives[1:], hr.After.Drives...) {
		if h.State != madmin.DriveStateOk {
			t.Fatalf("Unexpected drive state (%d): %v", i+1, h.State)
		}
	}

In most setups this is sufficient to heal the content after drive replacements. Setting `max_sleep` to a *lower* value and setting `max_io` to a *higher* value would make heal go faster.

- We limited the number of drives to 16 for erasure set because, erasure code shards more than 16 can become chatty and do not have any performance advantages. Additionally since 16 drive erasure set gives you tolerance of 8 drives per object by default which is plenty in any practical scenario.
