All replication failures are picked up by the scanner which runs at a one minute frequency, each time scanning upto a sixteenth of the namespace. Object versions marked `PENDING` or `FAILED` are re-queued for replication.

When using this feature, do not specify a port in the `server_addr` as the port is picked up automatically from the SRV record.

With the default (empty) value for `srv_record_name`, MinIO **will not** perform any SRV record request.
