| `hdds.datanode.failed.data.volumes.tolerated` | -1 | `DATANODE` | The number
of data volumes that are allowed to fail before a datanode stops offering
service. Config this to -1 means unlimited, but we should have at least one
good volume left. |

+| `hdds.datanode.grpc.so.backlog` | 4096 | `DATANODE` | The SO_BACKLOG value
for the Datanode gRPC server socket. This limits the number of pending

machine. Defaults to current hostname. |

address and the base port where the Datanode web ui will listen on. If the port
