## HTTP Trace

HTTP tracing can be enabled by using [`mc admin trace`](https://docs.min.io/community/minio-object-store/reference/minio-mc-admin/mc-admin-trace.html) command.

Example:

```sh
minio server /data
```

        failoverStates.remove(channel.getChannelId());

        // Try to establish a replacement channel
        manager.establishReplacementChannel();
