--------------------------------
Summary: EC: "Missing" EC containers with some remaining replicas
may block decommissioning
Key: HDDS-7666
URL: https://issues.apache.org/jira/browse/HDDS-7666
Project: Apache Ozone
Issue Type: Sub-task
Affects Versions: 1.3.0
Reporter: Ethan Rose
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.
