## Restart a canceled or failed decommission

```
λ mc admin decommission start alias/ http://minio{1...2}/data{1...4}
```

## When decommission is 'Complete'

Once decommission is complete, it will be indicated with *Complete* status.  *Complete* means that now you can now safely remove the first pool argument from the MinIO command line.

```
λ mc admin decommission status alias/
