> In EC, a container is considered missing and under replicated if it has lost enough replicas that offline reconstruction is not possible. If any of the remaining replicas for this container are on a datanode that is being decommissioned, the decommissioning will not proceed. All the containers on that node must be restored to proper replication for it to finish decommissioning, but the code will not copy the replica of the missing container to a different node.
