/**
* Miscellaneous disk-related IOException occurred when handling a request.
* Client should request metadata update and retry if the response shows KafkaStorageException
*
* Here are the guidelines on how to handle KafkaStorageException and IOException:
*
* 1) If the server has not finished loading logs, IOException does not need to be converted to KafkaStorageException
* 2) After the server has finished loading logs, IOException should be caught and trigger LogDirFailureChannel.maybeAddOfflineLogDir()
* Then the IOException should either be swallowed and logged, or be converted and re-thrown as KafkaStorageException
* 3) It is preferred for IOException to be caught in Log rather than in ReplicaManager or LogSegment.
