Improve the concurrent access on FsVolumeList

    Details

    • Target Version/s:

      Description

      FsVolumeList uses synchronized to protect the update on FsVolumeList#volumes, while various operations (e.g., checkDirs(), getAvailable()) iterate volumes without protection.

      This JIRA proposes to use AtomicReference to encapture volumes to provide better concurrent access.
