      Description

      This Jira tracks a few improvements to DataNode’s usage of DiskChecker to address the following problems:

      1. Checks are serialized so a single slow disk can indefinitely delay checking the rest.
      2. Related to 1, no detection of stalled checks.
      3. Lack of granularity. A single IO error initiates checking all disks.
      4. Inconsistent activation. Some DataNode IO failures trigger disk checks but not all.
