             Summary: When there is an existing dir, if it fails, server should not initialize a new dir
                 Key: RATIS-1668
                 URL: https://issues.apache.org/jira/browse/RATIS-1668
             Project: Ratis
          Issue Type: Improvement
          Components: server
            Reporter: Tsz-wo Sze
            Assignee: Tsz-wo Sze


[~NeilJoshi] reported this in HDDS-7103.

Currently, when there is an existing directory dirA, if dirA fails for some reason, RaftServer will try to initialize another directory dirB from the list specified in the configuration properties. Suppose dirB can be initialized successfully. The server can start at that time. However, when the server restarts, it may find dirA and dirB exist at the same time and then throw an exception. It is because the server cannot decide which one to use.
