   2. checksum failure after hsync/hflush, tracking in [HDDS-15857](https://issues.apache.org/jira/browse/HDDS-15857) and [HDDS-16258](https://issues.apache.org/jira/browse/HDDS-16258)
   3. need to handle retry when request goes to DN raft group follower, workaround in https://github.com/apache/ozone/pull/10743/changes/6ccafd44589f7bfa59975f0e719c4b890e67b4cf
