[jira] [Created] (HDDS-6611) Support changing names of hdds.datanode.dir directories

--------------------------------

             Summary: Support changing names of hdds.datanode.dir directories
                 Key: HDDS-6611
                 URL: https://issues.apache.org/jira/browse/HDDS-6611
             Project: Apache Ozone
          Issue Type: Improvement
          Components: Ozone Datanode
            Reporter: Ethan Rose


Currently the .container files of KeyValueContainers contain absolute paths to the chunks directory and metadata directory, which is used to find the container's contents after reading the container file. This means that if the mount points of volumes specified in hdds.datanode.dir configs change, the datanode will find the container files and try to load the containers, but report that the container is missing pieces because the container file's chunks and metadata directories no longer exist.
